Calibration Procedures 3
Calibration Message
The instrument allows you to store a 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. The calibration message may
contain up to 40 characters.
You can record a calibration message only when the instrument is
unsecured. You can read the calibration message whether the instrument
is secured or unsecured.
See “To Read the Calibration Message” on page 54 and “To Store a Calibration
Message” on page 54. Use the CALibration:STRing and
CALibration:STRing? commands from the remote interface.
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 2
32
(over 4 billion)
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.
See “To Read the Calibration Count” on page 53. Use the
CALibration:COUNt? command from the remote interface.
