Verifying DC current 10uA-100uA 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.
To verify DC current accuracy:
1. Setup the U.U.T. (Unit Under Test) for DC Current and the range being tested. Make sure
REL is disabled.
2. Verify the Zero testpoint for each range without any connection to the equipment and verify
the readings fall within specified limits.
3. Connect the Series 3700 AMPS and LO INPUT pins to the DC current calibrator as shown
in the figure titled DC current verification 10µA-100µA ranges.
4. Setup the HP3458A to the DC Current function and range.
5. Set the calibrator to source zero current and rel both the UUT and the HP3458A.
6. Source DC current for each of the test points summarized in the DC current verification data
table. For each setting, be sure that the reading is within stated limits.
