Verify DC voltage zeros using the 4-wire short
To verify DC voltage:
1. Leave the short applied as described in
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.
