Verify dc voltage zero values using the 4-wire short
To verify dc voltage zero values:
1. Leave the short connected as described in Verify resistance zero values using a 4-wire short (on
page 2-45).
2. Press the
FUNCTION
key.
3. Select the
DC Voltage
function.
4. Press the HOME key.
5. Set the range to 1000 V .
DC voltage verification is done in descending range order, starting with the 1000 V range and
finishing on the 100 mV range.
6. Verify that the 1000 V range zero is within specification. See the table below.
7. Verify that the 100 V to 100 mV range zero is within specification.
