A good precaution is to use a GPIB program (see the programming example titled
NOTE

change the security code by entering a new code while the Counter is unsecured
(CODE: )
view the calibration count, which indicates the number of times that the Counter
has been calibrated (CAL COUNT?). The calibration count increments up to a
maximum of 32,767 after which it wraps around to 1. A calibration count of 0
indicates that the Counter is completely uncalibrated. (The calibration count is
unaffected by interpolator calibration.)
get Help (HELP:) with any of the following:
– how to calibrate (CAL?),
– how to secure (SECURE?), and
– how to change the code (CODE?)
