The Megger 210170 insulation resistance tester is ideal for applications where high ohm ranges are necessary. It generates a regulated high DC voltage and uses low-zero-drift, high-accuracy circuits, with high current sensitivity. Power is supplied by a hand cranked, gear train AC generator. Test results are displayed via an analog meter, calibrated in megohms, ohms and AC volts. It features a guard terminal to eliminate surface leakage current from the measurement.

The 210170 measures the insulation resistance of wires, power cables, motors, generators, transformers, switchboards and electrical controls. It offers multiple test voltages for performing spot and step-voltage tests. Typical applications include:

  • Acceptance testing at time of installation to check conformance to specifications
  • Routine preventive maintenance testing after installation
  • Quality assurance testing by the manufacturer
  • Diagnostic testing to isolate faulty components for repair

This insulation tester can be used for detecting high- or low-resistance grounds, short circuits in apparatus, cables, wiring, etc. whether caused by moisture, oil, dirt, corrosion, damage to insulation or natural deterioration. It can also be used to determine the presence of moisture, solvents and semiconducting foreign materials in wires, cables and other conductors, and in built-up insulation systems such as those found in motor windings.
