Calibration Procedure
The following procedure is the recommended method to complete an
instrument calibration.
1 Read “Test Considerations” (page 71).
2 Unsecure the instrument for calibration (page 51).
3 Perform the verification tests to characterize the instrument
(incoming data).
4 Perform the zero adjustment procedures.
5 Perform the gain adjustment procedures. Perform the verification
tests to verify the adjustments (outgoing data).
6 Secure the instrument against calibration.
7 Note the new security code and calibration count in the
instrument’s maintenance records.
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 turning off the power. When performing a calibration
from the remote interface, you can abort a calibration by issuing a
remote interface device clear message.
CAUTION
If you abort a calibration in progress when the instrument is attempting
to write new calibration constants to EEPROM, you may lose all
calibration constants for the function. Typically, upon re-applying
power, the instrument will report error 705 Cal:Aborted. You may
also generate errors 740 through 746. If this occurs, you should not use
the instrument until a complete re-adjustment has been performed.
