from the attached module. The first time the OPT Key is pressed, a
series of messages is displayed listing the configuration of the module.
The first display is:
The top line shows that a 20 Milliamp/10 Volt Output module is
attached to the calibrator. The second display is:
The top line shows the serial number of the module and the second line
shows the date of the last calibration. The displays will remain for
approximately 1 second each, and then the final display will show:
When the OPT key is pressed subsequently, the calibrator checks the ID
and serial number of the attached module. If these match the previous

To utilize the features of the module after it has been activated with
the OPT key, the operator simply selects the milliamp or volts output
function using the calibrator’s keypad.
To generate a milliamp output, press the mA key while the calibrator is
in the output mode. The calibrator will prompt for the value desired.
