1-12 Performance Verification
Verifying DC current
Check DC current accuracy by applying accurate DC currents from the DC current calibrator
to the AMPS input of the Model 2015 and verifying that the displayed readings fall within spec-
ified limits.
Follow these steps to verify DC current accuracy:
1. Connect the Model 2015 AMPS and INPUT LO jacks to the calibrator as shown in
Figure 1-3.

Connections for DC current verification
2. Select the DC current measurement function by pressing the
DCI
key, then choose the
SLOW integration rate with the RATE key.
3. Set the Model 2015 for the 10mA range.
4. Source positive and negative full-scale currents for each of the ranges listed in Table
1-4, and verify that the readings for each range are within stated limits.
