Viewing calibration dates and calibration count
When calibration is locked, only the UNLOCK and VIEW-DATES selections will be
accessible in the calibration menu. To view calibration dates and calibration count at any time:
1. From normal display, press MENU, select CAL, and then press ENTER. The unit will
display the following:

UNLOCK EXECUTE VIEW-DATES ©
2. Select VIEW-DATES, and then press ENTER. The Model 2400 will display the next
and last calibration dates and the calibration count as in the following example:
NEXT CAL: 12/15/96
Last calibration: 12/15/95 Count: 00001
Calibration errors
The Model 2400 checks for errors after each calibration step, minimizing the possibility that
improper calibration may occur due to operator error.
Front panel error reporting
If an error is detected during comprehensive calibration, the instrument will display an
appropriate error message (see Appendix B). The unit will then prompt you to repeat the
calibration step that caused the error.
Remote error reporting
You can detect errors while in remote by testing the state of EAV (Error Available) bit (bit 2) in
the status byte. (Use the *STB? query to request the status byte.) Query the instrument for the
type of error by using the appropriate :SYST:ERR? query. The Model 2400 will respond with
the error number and a text message describing the nature of the error. See Appendix B for
details.
