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 it 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 six counts.
Remote interface operation
Calibration message
The power supply allows you to store one message in calibration memory in the
mainframe. For example, you can store such information as the date when the last
calibration was performed, the date when the next calibration is due, 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 a calibration message only from the remote interface and only
when the power supply is unsecured. You can read the message from either
the front panel or over the remote interface. You can read the calibration
message whether the power supply is secured or unsecured.
– The calibration message may contain up to 40 characters. From the front
panel, you can view 11 characters of the message at a time.
– Storing a calibration message will overwrite any message previously stored in
memory.
– The calibration message is stored in non- volatile memory, and does not
change when power has been turned off or after a remote interface reset.
