With the ATT function enabled, a test of 15mA or less is applied between line & earth. It enables loop impedance measurements without tripping RCDs rated at 30mA and above.

ATT supports measurements using three wires: Line, Earth, and Neutral and also two wires: Line and Earth.

Kyoritsu 6516 Multi Function Tester Features

Bluetooth communication

KEW 6516BT has a Bluetooth communication function and can exchange data with Android/ iOS tablet devices.

Before starting to use this function, download the special application “KEW Smart *” via the internet.

Large LCD & HELP function

• All the test data is shown in one large colored screen.
• HELP function will show how to connect the instrument according to the function selected

Operation in 3 simple steps & Hands free testing

1. Set the rotary dial to your testing range.
2. Connect the instrument to the installation under test.
3. Press the test button.(By remote probe or using the Lockdown function of the test button.)

Anti-Trip Technology (with 2 & 3 wire)

For no trip LOOP L-PE testing on all RCDs.
With 3 wire (L, N, PE), to get the best accuracy readings.
With 2 wire only, very useful in case of no Neutral (i.e. 3-phase motor lines).

Loop Impedance 0.001 resolution

High test current range of 2Ω with 0.001Ω resolution.

Zs/Ra Limit

Zs Limit compares the values required by Electrical Installations Standard with measured results.

The verification of safety requirement on an electrical installation is simplified by using Zs/Ra Limit function. This function will automatically check if the measured loop impedance for TN (or earth loop for TT) is low enough to trip (disconnect) the MCB / Fuse / RCD giving the result of PASS or FAIL on the display.

Continuity Measurement 
With the Kyoritsu 6016 Multi Function Electrical Tester continuity testing can be carried out by use of the test button lockdown feature. A selectable buzzer gives instantaneous indication of continuity. Null facility eliminates the test lead resistance from the results, the nulled value is retained even if the instrument is switched off. Live circuit warnings are given by a flashing LED, buzzer and indication on the display.

Insulation Measurement 
The Kyoritsu 6016 Multi Function Electrical Tester has three selectable test voltages 250V, 500V and 1000V. An auto-discharge function ensures that circuits are not hazardous after testing. A red LED gives warning of high voltage output during testing and discharging of the circuit. In case of connecting to a live circuit, a live circuit warning is given by flashing LED, buzzer and indication on the display.

Loop Impedance Measurement
The Kyoritsu 6016 Multi Function Electrical TesterA patented (ATT) low current loop impedance test enables high accuracy loop measurements and quick testing without tripping RCD’s.
A high current alternative is selectable for even higher accuracy and instantaneous results. The subsequent test will default to the low current test, this saves any inadvertent tripping of the RCD. The KEW 6016 allows also for phase to phase loop tests.

PSC / PFC Measurement 
The Prospective Short Circuit Current (PSC) and Prospective Fault Current (PFC) are automatically calculated and shown on the display. As loop testing, the function has low and high test current options with the default to low current to avoid inadvertent tripping of RCDs.

RCD Measurement 
The KEW 6016 has a comprehensive RCD test feature for RCD type AC (Alternative Currents), RCD type A (Pulsating Direct Currents), General and Selective (delayed).
Measures at 1/2x, 1x, 5x of nominal RCD current. It also has Ramp Test and Auto test where all results are shown on one screen. Touch voltage limit can be selected for 25V or 50V depending on application

Earth Measurement 
Using the classical Volt-Amper method with two auxiliary earth spikes and without external power source. All test leads and spikes are supplied as standard accessories.

Phase rotation 
KEW 6016 can check the phase rotation of three phase lines with clear indication of the sequence on the display.

Voltage Measurement 
In addiction to the voltage measurement, this function gives also the Frequency of the voltage under test.
