DC current 100 mA to 3 A range verification
You will:
• Apply accurate current from the DC current calibrator directly to the Model DMM7510 front-panel
terminals
• Verify that the displayed readings fall within specified limits
To verify DC current accuracy:
1. Set up the Model DMM7510 for DC current and the range being tested. Make sure relative offset
is disabled.
2. Connect the Model DMM7510 and calibrator as shown in the following figure.
Figure 9: 100 mA to 3 A range verification
Zero verify the Model DMM7510:
1. On the calibrator, select the OPR/STBY key. Ensure that the front panel displays STANDBY.
2. Set the ranges to 100 mA.
3. Verify the Model DMM7510 zero reading for each range.
Rel the system:
1. On the calibrator, select the OPR/STBY key. Ensure that the front panel displays OPERATE.
2. Set the calibrator to source zero current and rel the Model DMM7510.
3. Source DC current from the following "Verify DC current 100 mA range" table. For each setting,
be sure that the reading is within stated limits.
4. Repeat these steps for the 1 A and 3 A ranges.
