Metrel MI 3250 -10A Micro Ohmmeter Features:
- The Metrel MI 3250 is a highly efficient 10 A current source that generates 10A into 200 mΩ load for 15 min without overheating.
- High overvoltage protection (CAT IV / 300 V) allows measurement in substations and other points with low line resistance.
- Internal protection cicuit protects user and instrument from inadvertent connection to lines.
- Custom limits can be set for PASS / FAIL evaluation of test result.
- 50 Hz / 60 Hz ripple detection and rejection.
- Instrument can be powered from mains or internal rechargeable battery.
- Large 320 x 240 dots matrix LCD offers easy-to-read results and all associated parameters.
- Lightweight portable design.
- 10A Ductor
- Up to 1000 test results with timestamp can be stored in internal memory.
- PC SW HVLink PRO enables downloading, review, analyses and printing of test results.
Metrel MI 3250 MEASURING FUNCTIONS
- Bidirectional resistance measurement from 0,1 μΩ up to 2000 Ω with test current up to 10A
- Temperature compensation (with optional temperature probe)
Metrel MI 3250 TEST MODES:
• Manual mode is initiated by pressing the ’Test’ button after connecting the test leads to the unit under test. Continuity of C1 and C2 connectors is checked. Current is applied in both forward and reverse direction.
• Automatic mode: test starts automatically when probes are connected. Current is applied in both forward and reverse direction.
• Continuous mode allows repeated measurements to be made on the same sample. The measurement is updated every three seconds.
• Inductive mode is used for measuring resistance of inductive loads like motors and generators. Instrument generates selected current in one direction and waits voltage to stabilize, before measurement is preformed. To provide safety after measurement is completed instrument is equipped with auto-discharge facility.
