To view the calibration menu and security status from the counter
front panel
– The Calibration Menu softkeys and pertinent “Calibrate Information” are
accessed by pressing the [Utility] key and then the (Cal / AutoCal) softkey.
– The display shows the following:
– Cal Count shows the total number of times: (1) a successful calibration step
has been completed; (2) calibration data is downloaded; (3) the Cal String
or Secure Code is updated; (4) the counter firmware is updated. It is not
operator-modifiable and rolls over at (2
32
-1). Since the unit is calibrated
several times during manufacture, the Cal Count will not be zero when
shipped.
– Cal String shows the current calibration string. This string is
operator-modifiable, used to record such information as the date of the last
calibration, or by whom it was performed. The Calibration String can not be
entered from the front panel keys. It can only be entered/updated using the
remote SCPI command: CALibration STRing. Refer to the Keysight 53210A/
53220A/53230A SCPI Programmer’s Reference for details of the command
format.
