The General Radio 1862-C Megohmmeter was introduced in Catalog R (1963) and remained available through Catalog T (1968). It is a portable, direct-reading Megohmmeter featuring the patented Flip-Tilt (clam shell) case.
The 1862-C replaces the Type 1862-B with improved charge-discharge switching of the unknown. The lower test voltage has been increased from 50 V to 100 V.
Applications for the 1862-C include high value resistors and insulation resistance.
Specifications
- Ranges: 0.5 to 2,000,000 MΩ at 500 volts and to 200,000 MΩ at 100 volts.
- Accuracy: From ±3% at the low-resistance end of each decade to ± 12%; (See manual).
- Voltage on Unknown: 100 or 500 V, selected by switch on front panel.
