Chapter 4 Calibration Procedures
Calibration Message
Calibration Message
The instrument allows you to store one message in calibration memory.
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.

Calibration Count
You can query the instrument to determine how many calibrations have
been performed. Note that your instrument was calibrated before it left
the factory. When you receive your instrument, be sure to read the count
to determine its initial value.
• The calibration count increments up to a maximum of 65,535 after
which it rolls over to “0”. Since the value increments by one for each
calibration point, a complete calibration may increase the value by
many counts.
• The calibration count is also incremented with calibrations of the
DAC channels on the multifunction module.
