This message indicates that a calibration cycle has been initiated. If an
operator accidentally pressed the MODE switch, he/she now has the option to
abort the calibration cycle by pressing the CAL switch. The 921A will retain
the former calibration values and be prepared to test another device.
Whenever a different Configuration is installed, the display may instruct the
operator to recalibrate. The 921A will automatically prompt the operator if a
calibration is required due to a configuration change.
