The history of matrix adjustments contains the following information:
Note
The history of matrix adjustments of the chloride electrode is not output
with the calibration history of the sensor (NitraLyt+). If necessary, you
can create a log book message with the calibration history by means of
the menu item, Calib. history Cl in the setting table. How to do this is
described on page 3-10. The log book message is given in the log book
(message code IC5396).
Date Date of the matrix adjustment
S Slope [mV] of the electrode.
The slopes are marked by a star (*) because they were not changed
by the matrix adjustment or reset to the default condition with the
electrode zeroing.
DV Drift voltage [mV]
0 is displayed after an electrode zeroing.
Ref1 Reference concentration [mg/l]
Ref2 This column is of no importance for the matrix adjustment
Cl- Measured or entered chloride concentration [mg/l]
P Procedure (1 = matrix adjustment)
T Temperature [°C]
R Evaluation of the matrix adjustment
+ : Matrix adjustment successful.
The sensor measures with the new adjustment data.
? : Matrix adjustment unsuccessful.
Invalid adjustment data was discarded. Measurement is
continued with the last valid values.
