AE-1142B Low cost, High accuracy, DC Ohm Meter
3.4msec High Speed measurement.
- Measuring range：0.00mΩ～15.000MΩ
- 4-terminal measurement.
- Available to measure the percent the set reference value:
5mΩ～10MΩ±50.0％【Minimum resolution of 5μΩ】 - Temperature compensation（Sensor：Optional）【0ppm/℃～9999ppm/℃】
- Measurement not to influenced by thermal electromotive force.
- Impressed the measuring current at pulse interval, in order to reduce abrasion of measuring terminal.
- Contact-check is equipped as standard function.
- Comparison result by built-in comparator is open-collector output and displayed asLO,GO,HI by LED and buzzer.
- GP-IB /RS-232C/Centronics output available【Option】
