Series 3700 System Switch/Multimeter Reference Manual

Verifying DC current 1mA-3A ranges

Check DC current accuracy by applying accurate current from the DC current calibrator to the
Series 3700 analog backplane connector and verify that the displayed readings fall within
specified limits.
NOTE
To verify DC current accuracy:
1. Connect the Series 3700 AMPS and LO INPUT pins to the DC current calibrator as shown
in the figure titled DC current verification 1mA to 3A ranges using the Keithley Instruments
Model 3706-751 Fixture cable.
2. Select the DC current function.
3. Set the Series 3700 to the applicable ranges; make sure that REL is disabled.
4. Source DC current for each of the testpoints summarized in the DC current verification data
table. For each setting, be sure that the reading is within stated limits.
