Calibration Count
The calibration count feature provides an independent
“serialization” of your calibrations. You can determine the
number of times that your power supply has been calibrated.
By monitoring the calibration count, you can determine
whether an unauthorized calibration has been performed.
Since the value increments by one for each calibration
parameter (see Table 1- 4 on the next page), a complete
calibration increases the value by 5 counts.
The calibration count is stored in non- volatile memory and
does not change when power has been off or after a remote
interface reset. Your power supply was calibrated before it
left the factory. When you receive the power supply, read
the calibration count to determine its value.
The calibration count increments up to a maximum of 32,767
after which it wraps around to 0. No way is provided to
program or reset the calibration count.
Calibration Message
You can use the calibration message feature to record
calibration information about your power supply. For
example, you can store such information as the last
calibration date, the next calibration due date, the power
supply’s serial number, or even the name and phone number
of the person to contact for a new calibration.
You can record and read information in the calibration
message from the remote interface only.
The calibration message may contain up to 40 characters.
The calibration message is stored in non- volatile memory
and does not change when power has been off or after a
remote interface reset.
