The history of matrix adjustments contains the following information:
Note
If you set the potassium electrode to be displayed as the extra sensor
AmmoLyt+K, the calibration history of the potassium electrode can be
viewed under AmmoLyt+K. The IQ S
ENSOR N ET does not keep an extra
log book for this sensor. Log book messages are displayed with the
main sensor, AmmoLyt+.
If you do not set the potassium electrode to be displayed as an extra
sensor, you can create a log book message with the calibration history
by means of the menu item, Calib. history K in the setting table as
necessary. How to do this is described on page 3-10. The log book
message is given in the log book (message code IC5395).
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
K+ Measured or entered potassium 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.
