Four wire measurement eliminates lead and contact resistances
- Automatic zero circuit eliminates field test accuracies
- Broad line of test leads simplifies data collection
- Standard accuracy of ±0.25%
These rugged, portable ohmmeters provided accuracies of ±0.25% and resolution down to 0.1 µΩ. The ohmmeters are simple to operate, just connect the leads, turn the unit on, and read the measurement directly from the digital LED display. No warm-up is required. Applications include measuring the resistance of switch and circuit breaker contacts, transformers and generators, motor windings, busbar joints, aircraft, rail and pipe bonds, cable splices, metal alloys, graphite electrodes, and wire and cable.
