Calibration history
Fig. 4-6 330 - Calibration history of selected sensor
The calibration history contains the following information:
Note
Only calibration data produced by the same calibration procedure can
be compared.
Calibration data of
the initial calibra-
tion.
List with calibration
data of the last cali-
brations
Date Date of the calibration
S(*) Slope [mV] of the electrode
The value is marked by
* Values unchanged if it is not possible to
determine the slope. Instead, the last determined value is taken over
for the slope.
This applies to all 1 point calibration procedures,
1 point standard (1) ,
1 point ref. (2) and Simple std. add. (4) .
