When Your Standard Multimeter Isn’t Enough

Every electrical contractor and maintenance engineer has been there: an intermittent fault that defies diagnosis with a handheld multimeter, a motor inrush current that trips protection for no apparent reason, or a voltage sag on a commercial power supply that only appears during peak load periods. These aren’t problems you can solve with spot readings — you need to capture what’s actually happening on the waveform over time.

The HIOKI MR8880 Memory HiCorder is purpose-built for exactly these situations. It’s a portable, field-ready data acquisition recorder designed to simultaneously monitor multiple high-voltage channels, capture transient events with precise triggering, and deliver the kind of waveform data that turns guesswork into documented evidence.

Whether you’re investigating power quality issues in a commercial switchboard, verifying motor start-up behaviour for a commissioning report, or monitoring an uninterruptible power supply (UPS) for voltage drop events, the MR8880 puts laboratory-grade recording capability into a package that fits in your tool bag.

Direct 600 V Input — Leave the Differential Probes Behind

One of the most significant practical advantages of the MR8880 is its ability to accept direct voltage input up to 600 V AC/DC at CAT III safety ratings, with CAT IV coverage at 300 V AC/DC. For Australian electricians and maintenance professionals working on 415 V three-phase commercial and industrial supplies, this means you can connect directly to the power line without needing a separate differential probe.

That’s not just a convenience — it’s a genuine time-saver on site. Fewer accessories means faster setup, less equipment to carry, and reduced risk of connection errors. The four completely isolated analog channels let you measure all three phases of a power system simultaneously, with the fourth channel free for a neutral reference, control signal, or current waveform via an optional clamp sensor.

Rugged Enough for Australian Conditions

Australian job sites test equipment in ways that many manufacturers don’t design for. Summer temperatures inside a metal switchboard can easily exceed 40°C, while winter mornings in a Tasmanian substation might start below freezing. The MR8880 is rated for an operating temperature range of -10°C to 50°C, which covers the vast majority of field conditions you’ll encounter across the country.

The instrument also arrives with standard side protectors designed to absorb impacts and vibrations — it meets JIS automotive vibration standards, which speaks to its durability in transit and on active work sites. At just 1.66 kg with the battery pack installed, it’s light enough for extended carry without fatigue, yet substantial enough to feel like a professional-grade tool.

High-Speed Capture Meets Long-Term Monitoring

The MR8880 operates in two distinct measurement modes, giving you flexibility to match the recording approach to your investigation:

High-Speed Function: When you need to capture fast transient events — motor inrush currents, relay switching transients, or voltage spikes — the high-speed mode delivers sampling rates up to 1 MS/s (1 microsecond per sample) across all four channels simultaneously. The time axis ranges from 100 µs/div to 100 ms/div across 10 selectable ranges, with a sampling period of 1/100th of the selected range. This resolution ensures you won’t miss the critical details hidden within rapid electrical events.

Real-Time Function: For longer-duration monitoring tasks — tracking voltage stability over hours, logging RMS fluctuations during equipment commissioning, or capturing intermittent faults that occur unpredictably — the real-time recording function supports intervals from 100 µs to 1 minute across 19 selectable options. Data is saved continuously with simultaneous sampling across all channels, and you can write directly to external storage media (CF card or USB memory) at rates up to 10 kS/s for extended recording sessions.

With 14-bit resolution and 1 M-word per channel memory depth (1 word = 2 bytes), the MR8880 captures waveform detail with enough precision to reveal subtle anomalies that lower-resolution instruments would miss entirely.

Intelligent Triggering That Catches What Matters

The real power of a memory recorder lies in its triggering capability. The MR8880 offers advanced trigger settings that go far beyond simple level crossing. You can configure triggers based on voltage thresholds, RMS values, peak waveform levels, or logic signal states — and the pre-trigger function captures data from before the trigger event, so you get the full context of what caused the anomaly, not just what happened after.

This is particularly valuable for power quality investigations where you need to document the sequence of events leading up to a voltage drop, sag, or transient. The built-in cursor functions then let you identify numerical values of peak currents, timing intervals, and waveform characteristics directly on the 5.7-inch colour LCD display — no PC required for initial analysis.

PRESETS Configuration — Because Time on Site Is Money

HIOKI’s patented PRESETS function addresses a common frustration with advanced test equipment: the setup complexity. Rather than navigating through multiple menu layers to configure measurement ranges, trigger levels, time bases, and recording modes manually, PRESETS lets you select your measurement application — “Measure a commercial power supply,” “Monitor a power source for a voltage drop,” and so on — and guides you through the appropriate settings with on-screen instructions.

For a busy sparkie who doesn’t use a memory recorder every day, this dramatically reduces the risk of misconfiguration and gets you capturing useful data faster. It’s the difference between spending fifteen minutes wrestling with settings and being up and recording within a couple of minutes.

Eight Logic Channels for Control Signal Analysis

Beyond the four analog channels, the MR8880 includes eight built-in logic channels as standard. When paired with an optional logic probe (such as the MR9321-01 with four isolated channels), you can simultaneously monitor control signals, PLC outputs, relay states, and other digital events alongside your voltage and current waveforms.

This is essential for troubleshooting automated systems where you need to correlate a physical event (motor start, breaker trip, valve operation) with the control signal timing. The trigger system supports AND/OR logic conditions across both analog and logic channels, enabling precise event-based capture of complex sequences.

Flexible Power Options for Any Situation

Field accessibility is central to the MR8880’s design. It supports four different power supply options to suit virtually any measurement scenario:

The included AC adapter (Z1002) operates on 100–240 V AC globally, drawing 45 VA during real-time recording. The optional rechargeable NiMH battery pack (Z1000) provides approximately three hours of continuous use with the backlight on and recharges in about three hours via the AC adapter. For quick deployments, eight AA alkaline batteries deliver roughly 40 minutes of operation. There’s also a DC power input (10–28 V DC) for vehicle-based or solar-powered applications.

When the AC adapter and battery pack are used together, the adapter takes priority while simultaneously charging the battery — a thoughtful design touch that ensures uninterrupted recording during extended monitoring sessions.

Data Management and PC Connectivity

Measurement data can be saved to CF cards (up to 2 GB) or USB memory sticks directly from the instrument. Real-time data can be written continuously to external media, and you can swap storage devices without interrupting the recording — a critical feature for multi-day monitoring tasks.

The USB 2.0 mini-B port enables direct PC connection for file transfer and remote instrument control. The optional Wave Processor 9335 software provides comprehensive waveform display, analysis, and format conversion capabilities on your computer, making it straightforward to generate professional reports and documentation for compliance records.

An optional A6-size thermal printer unit (MR9000) attaches directly to the MR8880 for printing waveform records on site — useful for immediate documentation during commissioning or fault investigation.

Extensive Current Measurement Ecosystem

While the MR8880’s built-in channels handle voltage measurement directly, HIOKI offers a comprehensive range of compatible current sensors covering everything from milliamp leakage currents to 2,000 A load currents. High-precision AC/DC sensors with frequency response up to 2 MHz are available for motor drive and inverter analysis, while simpler clamp-on probes suit general load current monitoring.

This modular approach means you can configure the MR8880 precisely for your application — whether that’s a simple three-phase voltage and current power quality study, a detailed motor start-up analysis with high-bandwidth current capture, or a combined analog and logic signal investigation on an automated production line.

If you’ve ever felt that moment of tension when connecting test leads to live terminals, you know the drill. One slip, one accidental contact between probes, and you’re dealing with an arc flash, a blown circuit, or worse. For electrical contractors, facility managers, and energy auditors working on energized systems, this risk comes with the territory—until now.

The HIOKI PW3365 Clamp-On Power Logger fundamentally changes how Australian professionals approach power measurement. As the world’s first power logger with completely non-metallic contact voltage sensors, this instrument eliminates the physical risk that’s plagued power testing since day one. No exposed metal contacts. No direct terminal connections. No accidental short circuits.

Instead of fumbling with traditional voltage probes that need precise terminal placement, the PW3365 uses innovative fully-insulated voltage clips that attach anywhere along insulated cables or busbars. Clip around the wire jacket, not onto exposed metal—it’s that straightforward. This breakthrough design means you can measure 3-phase power systems while circuits remain energized and covered, without ever removing terminal guards or exposing live parts.

Real-World Problem: Why Traditional Power Testing Creates Dangerous Situations

Every sparky and facility tech knows the scenario: you need to log power consumption on a 3-phase distribution board to identify energy waste or verify equipment performance. Traditional power analyzers require you to:

1. Isolate the circuit or work live with exposed terminals
2. Carefully position voltage probes on metal contact points
3. Maintain safe clearances while managing multiple leads
4. Risk short circuits if probes slip or make unintended contact
5. Navigate around terminal covers that block access

This process isn’t just time-consuming—it’s genuinely hazardous. Australian electrical safety regulations (AS/NZS 3000:2018) emphasize risk elimination wherever possible. Working on live circuits with traditional test equipment places technicians in harm’s way for routine measurements. Facility managers conducting energy audits face tough decisions: shut down critical equipment for testing, or accept the risks of live testing.

The PW3365 solves this by making voltage measurement genuinely non-contact. The fully-covered PW9020 voltage sensors clip around insulated cables without any metal-to-metal connection. Short circuits become physically impossible because there’s no exposed metal on the voltage sensing clips.

How the PW3365’s Non-Contact Technology Works in Practice

Traditional Power Measurement:

• Voltage test leads with metal tips
• Must connect to bare metal terminals
• Risk of accidental shorts between phases or phase-to-ground
• Requires removing protective terminal covers
• Impossible to test through cable insulation

HIOKI PW3365 Approach:

• Fully-insulated voltage clips with zero exposed metal
• Clip directly around insulated cables or busbars
• Physically impossible to create short circuits
• Works through cable jackets—no need to access terminals
• Install sensors while equipment remains fully protected

This isn’t just a safety improvement—it’s a workflow transformation. Energy consultants conducting building audits can quickly clip sensors onto distribution cables without coordinating downtime. Industrial maintenance teams monitoring motor loads don’t need isolation permits. Solar installers verifying inverter output can test while systems remain energized.

Comprehensive 3-Phase Power Monitoring Without the Complexity

Beyond the safety innovation, the PW3365 delivers the measurement capabilities Australian electrical professionals actually need for real-world applications:

Complete Power Quality Analysis:

• Single-phase through 3-phase 4-wire circuit configurations
• Voltage range: 90V to 520V AC at 50/60Hz (perfect for Australian 230V/400V systems)
• Current measurement: 50mA to 5,000A (using appropriate Hioki clamp sensors sold separately)
• Harmonic analysis up to 13th order for identifying power quality issues
• Total harmonic distortion (THD) measurement for assessing waveform purity
• Power factor monitoring with lag/lead indication

Key Measurement Parameters: The PW3365 displays all the power parameters you need for comprehensive energy analysis: voltage (RMS and fundamental), current (RMS), active power, reactive power, apparent power, power factor (true or displacement), frequency, phase angle, and cumulative energy consumption. For demand monitoring, it tracks active and reactive power demand in user-defined intervals, essential for identifying peak loads and understanding utility demand charges.

Critical for Australian Energy Audits: When conducting facility energy assessments required for NABERS ratings, ESG reporting, or simple cost reduction initiatives, you need accurate data on actual power consumption, not nameplate estimates. The PW3365 logs this data continuously on SD cards (up to 8GB), providing months of detailed trend data showing exactly when and where energy is consumed. This long-term logging capability transforms one-time spot checks into comprehensive consumption profiles.

Quick Setup Eliminates 3-Phase Measurement Mistakes

Anyone who’s attempted 3-phase power measurement knows the challenge: six different wiring configurations, multiple leads to track, and one wrong connection that invalidates your entire dataset. The PW3365’s Quick Setup wizard walks you through the process step-by-step:

1. Select your circuit configuration (single-phase, 3-phase 3-wire, 3-phase 4-wire)
2. Follow on-screen diagrams showing exactly where to connect each sensor
3. Verify connections—the logger checks for errors and displays FAIL if connections are incorrect
4. Start logging with confidence that data will be accurate

This guided setup is particularly valuable when training new technicians or when working on unfamiliar equipment configurations. The instrument essentially becomes a measurement checklist, reducing the likelihood of test errors that waste time and produce questionable data.

Harmonic Analysis for Modern Power Systems

Australian commercial buildings and industrial facilities increasingly rely on variable frequency drives (VFDs), LED lighting, server equipment, and renewable energy inverters—all sources of harmonic distortion that traditional power monitoring overlooks. The PW3365’s harmonic measurement (up to 13th order) identifies these issues:

• 5th and 7th harmonics are the primary culprits in power quality problems, causing transformer overheating, neutral conductor overloading, and motor vibration
• Total Harmonic Distortion (THD) quantifies overall power quality, critical for compliance with AS/NZS 61000 standards
• Harmonic content display shows both numerical lists and graphical representations, making it easy to spot problem frequencies

For solar installers, harmonic analysis verifies that inverter output meets Australian grid connection requirements (AS 4777.2). For facility managers, it identifies equipment causing power quality issues before they trigger failures or increase losses.

Data Management That Actually Works on Job Sites

Power loggers live or die on their ability to capture data reliably and deliver it in usable formats. The PW3365 handles this through multiple approaches:

On-Board Storage:

• SD/SDHC memory cards up to 8GB capacity
• Internal memory backup (approximately 320KB)
• Configurable logging intervals from 1 second to 60 minutes
• Months of continuous data capture on a single SD card

Flexible Data Intervals: Save intervals of 1/2/5/10/15/30 seconds or 1/2/5/10/15/20/30/60 minutes mean you can balance data resolution against storage capacity. For short-term troubleshooting, log at 1-second intervals to catch transient events. For long-term energy audits, 15 or 30-minute intervals provide sufficient detail while maximizing storage duration.

Multiple Connectivity Options:

• LAN interface for remote monitoring and data download
• USB 2.0 for direct computer connection and data transfer
• SD card removal for simple file transfer to any computer
• HTTP server function allows web browser access to real-time data

The free HIOKI SF1000 software (downloadable) converts logged data into trend graphs, daily/weekly/monthly reports, and export formats for further analysis. For more comprehensive analysis, the optional SF1001 application provides advanced harmonic analysis, custom report generation, and multi-logger data compilation.

Built for Australian Conditions and Real-World Use

Compact Yet Rugged Design: Dimensions of 180mm (W) × 100mm (H) × 48mm (D) make the PW3365 compact enough to fit into crowded electrical cabinets or carry in a tool bag. The slim profile means it can be mounted inside panels or placed on equipment enclosures without consuming valuable space.

Flexible Power Options:

• Standard operation: Z1008 AC adapter (included) for bench or cabinet mounting
• Battery operation: Optional PW9002 battery set provides approximately 3 hours of portable operation
• Continuous charging: Battery charges while connected to AC power, whether instrument is on or off

Environmental Resilience: Operating temperature range from 0°C to 40°C with storage down to -10°C to 50°C suits Australian climates from Darwin’s tropical heat to Melbourne’s cool winters.

Measurement Update Speed: Approximately 0.5 second measurement update rate (except during SD card access or communications) provides near-real-time monitoring for observing load variations and power fluctuations.

Critical Measurement Accuracy for Professional Applications

When you’re making equipment purchasing decisions, verifying contractor work, or producing compliance documentation, measurement accuracy determines whether your data is defensible. The PW3365 delivers professional-grade accuracy:

Combined System Accuracy (PW3365 + PW9020 Voltage Sensors + Hioki Clamp Sensors):

• Voltage: ±1.5% rdg. ±0.2% f.s.
• Current: ±0.3% rdg. ±0.1% f.s. (plus clamp sensor accuracy)
• Active Power: ±2.0% rdg. ±0.3% f.s. (at unity power factor, plus clamp sensor accuracy)

These specifications mean your power consumption measurements are reliable enough for:

• Energy audit reports requiring third-party verification
• Baseline and verification (M&V) protocols for energy performance contracts
• Utility billing validation and demand charge analysis
• Equipment commissioning and performance verification
• AS/NZS 3000 electrical installation compliance documentation

Compatible Clamp Sensors for Every Application

The PW3365 requires separate AC current clamp sensors (with BNC connectors) to complete measurements. This flexibility allows you to configure the logger for specific measurement ranges:

Hioki Compatible Clamp Sensors (sold separately):

• 9660 Series – 100A AC, compact design for circuit-level monitoring
• 9661 Series – 500A AC, ideal for distribution panel and feeder monitoring
• 9669 Series – 1,000A AC, suitable for large equipment and main switchboards
• CT6843/CT6844 – 500A/5,000A AC flexible current sensors for tight spaces or irregular conductor shapes
• 9694/9695-02 – High-precision sensors for critical accuracy applications

This sensor flexibility means a single PW3365 logger can be redeployed across vastly different applications—from monitoring individual branch circuits at 10A to logging main incomer feeds at several thousand amperes.

Who Benefits Most from the PW3365

Electrical contractors, maintenance teams, and facility managers across Australia face a critical challenge: proving electrical system performance and energy efficiency without disrupting operations. Traditional handheld meters give you a snapshot—but what happens over time?

How do you document power demand patterns for an entire site? How do you prove that solar installations are performing to specification, or that industrial equipment is running efficiently? Without documented evidence, you’re left guessing about power quality, demand spikes, and energy waste. You need continuous, site-wide monitoring that creates audit trails for compliance, diagnosis, and optimization—without requiring dedicated IT infrastructure or constant manual readings.

SOLUTION OVERVIEW

The HIOKI PW3360-20/500 Kit delivers continuous, automated power monitoring that transforms how you approach energy audits, compliance documentation, and system diagnostics. Instead of snapshot readings, you capture detailed power data across hours, days, or weeks—stored directly on SD cards for later analysis and reporting. The integrated 500 A clamp sensors eliminate the need for separate equipment orders; everything you need is included and ready for deployment on Australian electrical systems.

This compact 550 g logger fits into confined plant rooms and ceiling cavities, making it practical for real-world job sites where access is limited. The QUICK SET feature walks you through 3-phase connections step-by-step, preventing the wiring mistakes that compromise data accuracy. HIOKI’s robust design handles typical Australian site conditions—industrial vibration, temperature fluctuations, and high-use environments—while maintaining ±0.3% measurement accuracy.

Whether you’re proving solar system performance under AS/NZS 5033, documenting industrial energy baseline for efficiency programs, or verifying power factor compliance across facility circuits, the PW3360-20/500 provides defensible, traceable evidence.

KEY BENEFITS & FEATURES

• Continuous Multi-Phase Monitoring That Captures Real Patterns Unlike spot checks, the PW3360-20/500 logs voltage, current, power, and demand simultaneously across three channels. You see actual consumption patterns, not averages. For solar installers verifying system integration into grid-connected properties, this means documenting instantaneous power injection and demand interaction—critical data under AS/NZS 5033. For facility managers, it reveals demand peaks that inform capacity planning and efficiency opportunities.
• 500 A Clamp Sensors—Everything Included, No Separate Orders The kit includes full-capacity 9661 clamp sensors up to 500 A, eliminating the frustration of incomplete equipment and unexpected costs. You mount the logger once, then monitor multiple circuits or phases without repositioning the base unit. The multicolored clips and spiral tubes keep everything organised on site, reducing setup time and improving measurement accuracy.
• 3-Phase Capability for Real Australian Industrial Sites Single-phase equipment matters, but most Australian industrial and commercial properties run 3-phase circuits. This logger simultaneously captures all three phases, giving you complete system visibility. No guesswork. No jumping between measurements. Complete load distribution data in one session.
• Data Logging That Creates Compliance Audit Trails Store months of raw data on the included 2 GB SD card. Access real-time and historical graphs on the 3.5″ color display, or transfer data to your computer via USB/LAN for professional reporting and analysis. The GENNECT One SF4000 software (included) transforms raw data into graphs and reports suitable for compliance documentation, client handover, and internal analysis.
• Engineered for Australian Field Conditions At just 550 g, it’s portable enough to carry between job sites yet robust enough for harsh industrial environments. The compact design (180 mm × 100 mm × 48 mm) fits into spaces where bigger equipment can’t reach—crucial in retrofit projects and confined plant rooms. Battery operation (6 hours continuous) or AC power gives you flexibility on sites with variable power availability.
• Wiring Check & QUICK SET—Eliminates Setup Errors Three-phase connections are straightforward once you understand the logic, but mistakes happen. HIOKI’s on-screen QUICK SET guides you through connections, and the wiring check function flags errors before measurement begins. This small feature has prevented countless days of wasted effort from corrupted data.

 APPLICATIONS & USE CASES

Solar Installation Performance Verification (AS/NZS 5033 Compliance) Installers must document system performance and grid interaction. The PW3360-20/500 logs real-time power injection, voltage stability, and phase balance over days or weeks—providing the evidence of compliant operation required by standards and insurance. Compare baseline grid consumption against post-installation data to prove system contribution and customer benefit.

Industrial Energy Audits & Efficiency Programs Facility managers identify where energy is wasted—often in demand peaks and power factor issues. This logger captures demand profiles across all phases over extended periods, revealing patterns that spot checks miss. Armed with actual data, you negotiate better supply contracts, justify equipment upgrades, or prove energy savings post-efficiency intervention.

Power Quality Investigation on Critical Circuits When equipment fails prematurely or behaves erratically, power quality often plays a hidden role. Log voltage stability, frequency variation, and harmonic content (with PW3360-21 option) to diagnose whether site conditions are contributing to failures. This data supports warranty claims and informs maintenance strategies.

Load Distribution & Electrical Compliance Testing Commercial buildings must prove balanced load across phases under AS/NZS 3000. The simultaneous 3-phase logging shows actual distribution and identifies circuits contributing to imbalance, enabling remedial rewiring or load rebalancing documentation.

Preventive Maintenance & Baseline Establishment Before critical equipment fails, establish a power consumption baseline. Regular logging detects gradual changes—a sign of motor degradation, bearing wear, or control system drift—allowing planned maintenance before failure.
