2 general radio 1644 a megohm bridges one lot
Up for sale are (2) Two General Radio Bridge MegOHM Bridge's. I plugged them in and they turned on but this is the extent of my testing ability.
Serial Number: 486 and Serial Number 430
Information I found on the web for research below:
Seven fixed test voltages are available (10 to 1000 V)
* Although any voltage between 10 and 1000 V may be obtained using an external resistor.
* Resistance range of 10E+03 to 10E+15 ohms with 1% accuracy to 10E+12 ohms (Delta R measurements to 0.2%)
* Utilizes self-checking internal standards
The General Radio 1644A, Megohm Bridge, that is ideally suited to measure a wide range of resistance from the insulation resistance of cables, to high-valued resistors, diodes, transistors, to voltage and temperature coefficients of resistance, to volume and surface resistivity of solids.

Seven fixed test voltages are available (10 to 1000 V), although any voltage between 10 and 1000 V may be obtained using an external resistor. Resistance range of 1 kilohm to 1 Petaohm with 1% accuracy to 1 Teraohm(Delta R measurements to 0.2%). Utilizes self-checking internal standards.
