Calibration Process
28 34450A Service Guide
If you abort a calibration in progress, all calibration constants for the
selected function range are lost. If power is turned off when the
instrument is attempting to write new calibration constants to EEPROM,
all calibration constants for the selected function range may also lost.
Typically, upon re–applying power, the instrument will report Calibration
Corrupt in the Questionable Data Register. Refer to the
STAT:QUES:COND? command in the 34450A Programmer's Reference Help
File for more details. If this occurs, you should not use the instrument
until a complete re–adjustment has been performed.
