Key features
Ultra‑wide range
Measure from 0.1 µΩ up to 1.2 GΩ on one instrument.
High throughput
Up to 220 readings/s with Fast/Med/Slow modes and comparator sorting.
Low‑ohms accuracy
4‑wire (Kelvin) measurement with short‑circuit clear and shielded inputs.
Automation‑ready
Handler I/O, RS‑232, SCPI, external trigger & temperature compensation input.
Why high‑precision micro‑ohms?
Detect problems you can’t see with standard DMMs
- Contacts & bonds: find micro‑ohm rises that lead to heat, arcing or early failure.
- Magnetics DCR: resolve copper resistance shifts and shorted turns.
- Production sorting: high‑speed binning for consistent pass/fail decisions.
- Stable results: Kelvin wiring + temperature compensation reduces lead & ambient effects.
