Keysight 53210A/53220A/53230A Assembly Level Service Guide
The current internal ambient temperature and the temperature at the last
Auto-Cal can be seen simultaneously using:
[Utility] / (Cal AutoCal) / (Measure Temp)
To run auto calibration:
1
Press the
Utility
key and then the
Cal / AutoCal
softkey to display the calibrate
options.
2
Press
Auto Cal
.
– Display stops updating until auto-calibration is completed (several seconds).
– If the calibration is successful, the screen displays “
Auto Calibration succeeded
”.
–
Cal Count
is not updated, but the calibration constants ARE updated.
– If any one of the calibration routines fails, the screen displays “
Auto Calibration
failed
”.
NOTE
It is recommended that Auto-Cal be performed frequently during routine counter
operation, especially if there has been an internal ambient temperature change
of 5
o
C or more since the last Auto-Cal. A good practice is to perform Auto-Cal at
the beginning of a new day of use, at an operator shift change, or other strategic
time. However, it may not be desirable to perform an Auto-Cal in the middle of a
series of measurements, since the cal constants are updated each time Auto-Cal
is performed.
