Calibration message
The instrument 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
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 message from either the
front-panel or over the remote interface. 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 13 characters of the message at a time. Press to scroll
through the text of the message. Press again to increase the scrolling
speed.
– Storing a calibration message will overwrite any message previously stored in
memory.
– The calibration message is stored in non-volatile memory in the mainframe,
and does not change when power has been off, after a Factory Reset (*RST
command), or after an Instrument Preset (SYSTem:PRESet command).
– Front-Panel Operation:
CAL MESSAGE
– Remote Interface Operation: To store the calibration message, send the
following command.
CAL:STRING ’CAL: 06-01-98’
