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.

To store a calibration message use the

CALibration:STRing command

and to read the calibration message, use the

CALibration:STRing?

command from the remote interface.

To read the 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, read the count to

determine its initial value.

The count value increments by one for each calibration point, and a

complete calibration will increase the value by many counts. The

calibration count increments up to a maximum of 2

- 1 after which it

rolls over to 0. The calibration count can be read either remotely or from

the front panel. To read the calibration count from remote, use the

CALibration:COUNt? command. Use the following procedure to read

the calibration count from the front panel.

1 In the Utility menu/Calibration mode display will show the calibration

count.
