1864 General Radio Insulation Meter


The 1864 is an insulation meter (Megohmmeter) 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.

Additional Features:

  • Easy to use
  • Rugged portable carrying case
  • Charge current up to 5 mA
  • High-accuracy: 0.01% (100 ppm)
  • 200 test voltages: 10 VDC to 1090 VDC
  • 50 kΩ to 200 TΩ
  • Analog output
  • 3 % basic accuracy
  • Simple operation
  • Direct reading, safe and reliable

The 1864 Megohmmeter is the choice for more demanding applications. The test voltage can be set to any value from 10 VDC to 109 VDC in 1 V steps and 10 VDC steps from 100 VDC to 1090 VDC. Thus, the1864 can be set to any common, or uncommon, test voltage for Ceramic, mica or paper capacitors, or other devices. The reverse resistance of rectifiers can be readily measured; the low test voltages available are especially useful in measuring solid-state diodes, An additional range permits measurements up to 2 x 10" ohms (200 To).
