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.
