1862C General Radio Insulation Meter

The 1862C is an insulation meter from General Radio. HiPot, or high potential, is a class of electronic test equipment used to verify electrical insulation. Engineers use HiPot-testing instruments on cables, wires, circuit boards, appliances, electric motors, and transformers. As a product ages, its insulation may break down and result in current flow leakage. HiPot testers keep engineers safe from current leakages by detecting gaps and defects in the electronic device. Dielectric Testers, Insulation Testers, and Megohmmeters are similar to HiPot testers. Popular manufacturers include Biddle, Megger, Fluke, Associated Research, Quadtech, Instek, and Slaughter.

Additonal Features:

  • Consists of a regulated power supply
  • A complement of resistance standards
  • A balanced, DC, vacuum-tube voltmeter with very high input resistance
  • Test voltages available are:
  • 100 VDC and 500 VDC
  • Resistance range:
  • 0.5 Mohm to 2 Tohm at 500 V
  • 0.5 Mohm to 0.2 Tohm at 100 V
  • 6 decade ranges
  • Accuracy is:
  • ±3% of indication at low resistance of each decade to ±12% (accuracy to which scale can be read) at high resistance end up to 50,000 Mohm
  • possible additional ±2% error at top decade. Voltage can be removed from terminals by setting of either switch to discharge position
