Capacitance Offset Calibration (Optional)
This calibration procedure applies to all models (34460A/61A/65A/70A).
This calibration is normally not required. It compensates for residual capacitance offset which is typically
less than a few pF. In normal use, any residual offset will be overridden by the null function (null also cor-
rects for cable capacitance), and the null function is required to achieve the multimeter’s capacitance spe-
cification.
Configuration: Capacitance
1.
Remove all connections from the instrument's front terminals.
2.
Select the front terminals.
3.
Enter a calibration value of +0 (see
). A Calibration Step Succeeded mes-
sage indicates success; if the display shows Calibration Step Failed, check the input value, range, func-
tion, and entered calibration value and repeat the calibration step.
4.
Repeat steps 1 through 3 for the instrument's rear terminals (not applicable to the 34460A).
5.
Store the new calibration constants (see
Storing the Calibration Constants
).
