Loop Resistance Testing Meter

Loop resistance testing meter is suitable for the contact resistance measurement of HV switchgears and circuit breakers. It can also measure the primary resistance of the current transformers.

Additional Product Information

Features & Benefits
  1. Large current test range;
  2. High output voltage, test wires are convenient to take onsite;
  3. Test current comes from high precision constant current power, no need for manual regulation;
  4. Four-pole wiring method to avoid the test wire resistance’s affection on the test results;
  5. Over heat protection for long time continuous operation;
  6. RS485 communication port, remote control is possible if it works with external upper computer control software.
Applications

Loop resistance testing meter is suitable for the contact resistance measurement of HV switchgears and circuit breakers. It can also measure the primary resistance of the current transformers.
