Additional calibration menu commands
Additional commands are available to save or reset parameters.
— Reset All. Resets the calibration for SP, DP, and Temperature:
– To Factory Cal. Resets all to the factory stored calibration values.
– To User Cal. Resets all to the user saved calibration values.
— Save to User. This command saves the calibration value for either SP, DP, or Temperature, depending on the sensor
menu involved. The data is stored for safekeeping in the nonvolatile memory. This should be performed after the user has
completed the calibration of all sensors.
— Reset to User. Resets the value for either SP, DP, or Temperature, depending on the sensor menu involved, to the values
saved by the Save to User command.
— Reset to Factory. Resets the calibration for either SP, DP, or Temperature, depending on the sensor menu involved, to the
values saved during the factory calibration.
The additional calibration menu commands listed above are detailed in Table 14, Calibration menu (page 59). It is important to
save user-defined calibration values in the nonvolatile memory so that the settings can be restored following a power failure.
Likewise, it may be beneficial to reset the unit to factory calibration standards. User calibration values are not saved unless the
command parameter is set.
