Remote interface operation
To change the security code, first unsecure the power supply
using the old security code. Then, enter the new code as
shown below.
Calibration count
You can determine the number of times that your power
supply has been calibrated. Your power supply was
calibrated before it left the factory. When you receive your
power supply, read the count to determine its initial value.
The calibration count feature can be performed from the
remote interface only.
• The calibration count is stored in non- volatile memory,
and does not change when power has been turned off or
after a remote interface reset.
• The calibration count increments up to a maximum of
32767 after which it wraps- around to 0. Since the value
increments by one for each calibration point, a complete
calibration will increase the value by five counts.
CAL:SEC:CODE <new code> Change the security
code.
CAL:SEC:STAT OFF, HP003632 Unsecure with the
old code.
CAL:SEC:CODE ZZ001443 Enter the new code.
CAL:SEC:STAT ON, ZZ001443 Secure with the new
code.
