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 3-3 on the next page), a complete calibration
increases the value by 6 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.
