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 powers 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 off or after a remote interface reset.
