Calibration Message
The instrument allows you to store one message in calibration memory 
in the mainframe, a digital module, or the internal DMM (remote interface
operation only). 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 instrument’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 instrument is unsecured. You can read the
calibration message whether the instrument is secured or unsecured.
• The calibration message may contain up to 40 characters. From the
front panel, you can view 18 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 in the
mainframe, a digital module, or the internal DMM, and does not change
when power has been off, after a Factory Reset (
*RST command), 
or after an Instrument Preset (
SYSTem:PRESet command).
Remote Interface Operation: The following example shows how to store a
message in calibration memory on the module in slot 3.
