11.2.2 Managing the calibration data
The calibration data is stored in the current calibration record (menu,
Calibration / Calibration record... ) and in the calibration history (menu,
Calibration / Calibration history... and Memory / Calibration memory ).
The current calibration record of ID sensors is stored in the sensor, of
non ID sensors it is stored in the ProLab 4000.
The meter creates a separate calibration history for each ID sensor cal-
ibrated with the ProLab 4000.
For non ID sensors calibrated with the meter, a calibration history is
created for each measured parameter (pH, ISE, Cond) where the cur-
rent calibration data is appended.
Managing functions for all calibration data are available to the adminis-
trator only.
Viewing the calibration
history
The administrator can view the calibration histories of all sensors and
users.
Erasing a calibration
history
The administrator can delete the calibration histories of all sensors and
users.
The current calibration data of each sensor is stored separately and is
retained even if the calibration history is deleted.
