The General Radio 1862-B Megohm Meter was introduced in Catalog N (1954) and remained available through Catalog Q (1961).
The Type 1862-B is update from 1862-A Type with the addition a 50 V to compliment the 500 V test voltage. Both instruments are designed for insulation test and high resistance tests. The meter is marked directly in megohms and the multiplier switch is color coded to the corresponding voltage on the unknown. The function switch has a calibrate setting and discharge setting with corresponding warning lamp.
Specifications
- Range: 0.5 MΩ to 2,000,000 MΩ at 500 V and to 200,000 MΩ at 50 V.
- Accuracy: At 5OO V, the basic accuracy is ±3% for all but the highest multiplier setting is ±3% (See Manual).
- Voltage at Unknown: 50 V or 500 V selected by front panel switch.
