Verify DC voltage zeros using the 4-wire short
To verify DC voltage:
1. Leave the short applied as described in Verify resistance zeros using a 4-wire short (on page 2-
62).
2. Select the DC Voltage function.
3. Set the range to 1000 V.
DC Voltage verification is from descending range order, starting with the 1000 V range and finishing
on the 1 V range.
4. Verify that the 1000 V range zero is within specification. See the table below.
5. Verify that the 100 V to 1 V range zero is within specification.

DC current 10 A range verification
To verify 10 A range:
1. Set the TERMINALS switch to REAR. Ensure that the orange R is displayed.
2. Press the FUNCTION key and select DC Current.
3. Press the HOME key.
4. Set the range to 10A.
5. Connect Model DMM7510, reference DMM, calibrator, and amplifier as shown in the following
figure.
