To change a forgotten passcode to a new passcode, you can turn on the instrument after shorting CAL SECURE
jumper J1 on the front panel board as shown below and send CAL:SEC:CODE <code> to change the passcode.
Calibration Count
You can query the instrument to determine how many calibrations have been performed. Note that your instrument
was calibrated before it left the factory. When you receive your instrument, read the count to determine its initial
value.
The count value increments by one for each calibration point, and a complete calibration will increase the value by
many counts. The calibration count increments up to a maximum of 2
32
-1 after which it rolls over to 0. The
calibration count can only be read remotely.
From the remote interface:
CAL:COUN?
Calibration Message
You can use the CALibration:STRing command to store a message of up to 40 characters in calibration memory. For
example, you could store the last calibration date, the calibration due date, or contact information for the person
responsible for calibration. The calibration message is not affected by a power cycle or *RST.
You can only store the calibration message when the instrument is unsecured, but you can execute the
CALibration:STRing? query regardless of whether the instrument is secured. A new calibration message overwrites
the previous message, and messages over 40 characters are truncated.
