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.
• Front-Panel Operation:
To read calibration message from the front panel, press and turn the knob
until ‘‘ CAL STRING ’’ is displayed. Press to scroll through the text of the
message. Press to increase the scrolling speed.
