Comprehensive calibration
The comprehensive calibration procedure calibrates the DCV, DCI, ACV, ACI, and ohms
functions You can also choose to calibrate only DCV/DCI and resistance, or the ACV/ACI func-
tions.
These procedures are usually the only ones required in the field. Manufacturing calibration is
done at the factory and should be done if the unit has been repaired in the field. See the Manu-
facturing calibration paragraph at the end of this section for more information.
Calibration cycle
Perform comprehensive calibration at least once a year, or every 90 days to ensure the unit
meets the corresponding specifications.
Recommended equipment
Table 2-1 lists the recommended equipment you need for comprehensive, DC only, and AC
only calibration procedures. You can use alternate equipment, such as a DC transfer standard
and characterized resistors, as long that equipment has specifications at least as good as those
listed in the table.
Canceling calibration
You can cancel the calibration process at any time by pressing EXIT.
