Vanguard Auto-Ohm 200 S3 Ampere Micro-Ohmmeter Ideal for Low-Current and High-Current Measurements

  • Uncategorized

Vanguard_220s3The Auto-Ohm-200 S3 Ampere Micro-Ohmmeter isVanguard’s fourth generation, microprocessor-based, true DC micro-ohmmeter. It is designed for testing EHV circuit-breaker contact resistances, bushing contact joints, welding joints, or for any low-resistance measuring application.

This high current and very lightweight (16.8 lbs/ 7.6 Kg) micro-ohmmeter is designed to meet the IEEE C57.09-1999 (5.15) requirement for testing circuit breaker contact resistance.

The Vanguard Auto-Ohm-200 S3 Ampere Micro-Ohmmeter can accurately measure resistance values from 1 micro-ohm to 5 ohms. A 0.1 micro-ohm resolution is possible with current greater than 5A. The Vanguard Auto-Ohm 200 S3 applies a selectable true DC test current from 1A to 200A to the resistance load to be tested.
