Model 7700 verification
Use these procedures to verify measurement accuracy through the Model 7700 20-Channel
Multiplexer Card.
NOTE

Verifying DC voltage

Check DC voltage accuracy by applying accurate voltages from the DC voltage calibrator to
the Model 7700 input terminals and verifying that the displayed readings fall within specified
limits.
CAUTION
Connect the function generator to the Model 2701 INPUT jacks. (See
sure the INPUTS switch is in the FRONT position.
Set the function generator to output a 1kHz, 1V RMS sine wave.
Select the Model 2701 frequency function by pressing the FREQ key.
Verify that the Model 2701 frequency reading is between 999.9Hz and 1.0001kHz.

Although the following tests are based on the Model 7700 20-Channel Multiplexer,
the same general procedures can be used for other plug-in modules that have similar
capabilities. Refer to the Model 2701 User's Manual for specific information on ter-
minals and connections for other plug-in modules.
Do not exceed 300V DC between plug-in module INPUT H and L
terminals or between any adjacent channels.
