Vanguard Auto-Ohm 200 S3

Product Overview: Vanguard Auto-Ohm 200 S3

Auto-Ohm 200 S3
Portable Micro-ohmmeter

The Auto-Ohm-200 S3 is Vanguard’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.

• Very lightweight: 16.8 lbs. (7.6 Kg)
• Measures circuit breaker contact resistance with safety ground on (with the Dual Ground option)
• Stores test records on-board or on external USB Flash drive
• 1 to 200A programmable test current
