Calibration Procedures
Before beginning any adjustment procedures, the multimeter must be in
the “
UNSECURED
” state. To unsecure the multimeter, see “Calibration
Security Code” on page 73. Each adjustment should be followed by a
performance verification check for added confidence. We recommend
that you always adhere to the following general procedure.
•
Make sure you have read “Test Considerations” on page 64.
•
Unsecure the multimeter as outlined in “Calibration Security Code”
on page 73.
•
Perform the Zero Adjustment Procedure.
•
Perform the Gain Adjustment Procedure.
•
Perform the Verification Tests.
•
Secure the multimeter.
•
Note the new secure code and calibration count in your maintenance
records for future reference.
Aborting a Calibration in Progress
Sometimes it may be necessary to abort a calibration after the
procedure has already been initiated. You can abort a calibration at
any time by pressing any front-panel key (except
Shift
). When
performing a calibration from the remote interface, you can abort a
calibration by issuing a remote interface device clear message or by
pressing the front-panel
LOCAL
key. Pressing the front/rear switch
during a calibration will also abort the calibration in progress.
