Information: INTRODUCTION The model is a six function, 5 1/2 digit resolution autoranging Digital multimeter to measure DC voltage from 1µV/count to V. AC voltage and current measurements are standard in the model TRMS ACV capability ranges from 1µV/count to V. The Model measures resistance from 1mΩ to MΩ on seven resistance ranges. The model has six current ranges that measure current from 1nA to 10A. The dB function makes it possible to compress a large. Fortunately, the service manual for Keithley is widely available. Here is the schematics of the original design: Basically, it uses a Maxim SI (now obsolete) charge pump to create the symmetric negative operating voltage (V). And the charging circuit is formed simply with resistors (RT and R along with the 10 Ohm resistor R on the main circuit board). This manual contains information necessary for operating and servicing the Model A Autoranging Microvolt DMM and the Rechargeable Battery Pack. This section of the manual contains general information and an initial operation procedure.
