Updating the Calibration Expired Action Setting
This item defines what indication is given during start up when calibration is
due and CL RMNDR is set to ON.
With CL EXPRD set to CONFIRM (factory setting), the GX-2012 will give
an indication at start up if calibration is due and require the user to press the
RESET SILENCE button to continue.
With CL EXPRD set to NOT USE, if the unit is due for calibration the GX-
2012 will give an indication at start up that calibration is due and the unit
cannot be used until it is calibrated. With this setting, it is necessary to
calibrate the instrument from Maintenance Mode if calibration is not
performed before it is due. See “Calibrating Using Auto Calibration” on
page 105 and “Calibrating Using Single Calibration” on page 108 for
instructions.
With CL EXPRD set to NO EFFECT, no confirmation during startup or
calibration is required to use the GX-2012.
