Vanguard Auto-Ohm 200 S2
Ohmmeter; Low Resistance, 200A -

The Auto-Ohm 200 S2 is Vanguard's third-generation, microprocessor-based, true DC micro-ohmmeter. It is designed for testing EHV circuit-breaker contact resistances, bushing contact joints, or for any low-resistance measuring application. The Auto-Ohm 200 S2 can accurately measure resistances ranging from 1 micro-ohm to 300 milliohms. It can output a test current from 10 Amperes to 200 Amperes.

The Auto-Ohm 200 S2 applies a true DC current from 10A to 200A to the resistance load to be tested. Any test current setting can be selected by using the function control knob on the front panel. The Auto-Ohm 200 S2 controls the test current's rise and fall rates by using a switching DC and a current regulator circuit. An Auto Test Mode is also available and can be initiated simply by applying the sensor cables€™ leads across the two points of interest. This feature is very convenient when measuring a sequence of several resistance values in a breaker contact.

  • 10 to 200 Amperes True Continuous DC Current
  • Automatic control of current rise and fall time
  • Digital Resistance Reading from 1 micro-ohm to 300 milli-ohms
  • Store and Display last 3 Readings
