Vanguard DMOM-100
Ohmmeter; Low Resistance, 100A –

The DMOM-100 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 DMOM-100 S2 can accurately measure resistances ranging from 1 micro-ohm to 300 milli-ohms. It can output a test current from 10 Amperes to 100 Amperes.

The DMOM-100 S2 applies a true-DC current from 10A to 100A to the resistance load to be tested. Any test current setting can be selected by using the unit’s alpha-numeric keypad. The DMOM-100 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.

Features

  • 10 to 100 Ampere True Continuous DC Current
  • Automatic control of current rise and fall time
  • Digital Resistance Reading from 1 micro-ohm to 300 milli-ohms
  • Stores 63 records (of 96 readings)
  • 2.5″ Built-in thermal printer
  • Weighs less than 17 lbs. (7.71 kg)
