Aborting a Calibration in Progress

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 followed by a
*RST.
The instrument stores calibration constants at the end of each
adjustment procedure. If you lose power, or otherwise abort an
adjustment in progress, you will only need to perform the interrupted
adjustment procedure again.
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 Calibration Aborted”.
Sequence of Adjustments
The adjustment sequence shown in the following sections of this chapter
is recommended to minimize the number of test equipment set-up and
connection changes.
You may perform individual adjustments as necessary. Setups 1 through 7
must be performed in order and must be performed before any other
setup procedure.
Note If you have repaired the output amplifier circuitry (U1903, U1904, and
associated components) you should perform the “Output Amplifier
Adjustment (Optional)”, on page 90 before beginning any other
adjustment procedures.
