Used General Radio Megohmmeter

Listing description

The GenRad 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-volt steps and to 1090 Vdc in 10 volt steps. Thus the GenRad 1864 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 are especially useful in measuring solid state diodes. An additional range on the 1864 Megohmmeter permits measurements up to 200 TO (2 x 1014 O).

Stability of calibration in the GenRad 1864 Megohmmeter is maintained by use of a four-transistor unity gain amplifier. In addition, no warm-up drift is encountered, and high zero stability is maintained during operation. Human engineering has not been overlooked in the GenRad 1864 Megohmmeter as evidenced by the warning light that is activated by the application of the test voltage. The 1864 employees a Measure/Charge/Discharge switch and provision for performance grounded and ungrounded measurements.

The GenRad 1864 Megohmmeter is easy to use with direct-reading meter indication and lighted range switch that shows the multiplier for each range and voltage. The maximum current possible at the terminals is limited to a 5mA and a panel light near the terminals warns when voltage is present.
