Zero Offset Verification
This procedure is used to check the zero offset performance of the
multimeter. Verification checks are only performed for those functions
and ranges with unique offset calibration constants. A low-thermal
EMF
four-terminal short is applied to the input of the multimeter.
Measurements are checked for each function and range as described in
the procedure below.

1 Make sure you have read “Test Considerations” on page 64.
2 Apply a 4-wire short (copper) across the
Input HI-LO and Sense HI-LO
terminals as shown below (front or rear terminal).
3 Select the shorted terminal set (front or rear) with the front/rear
switch. Separate zero offset calibration constants are stored for the
front and rear input terminals.
4 Select each function and range in the order shown in the table on
the next page. Compare measurement results to the appropriate
test limits shown in the table.
