The history of matrix adjustments contains the following information:
Note
If you set the potassium electrode to be displayed as the extra sensor
VARiON K, the calibration history of the potassium electrode can be
viewed under VARiON 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, VARiON A.
For the chloride electrode, or if the potassium electrode is not displayed
as an extra sensor, you can generate a log book message with the
calibration history by means of the menu item, Calib. history Cl (or K)
in the setting table of the relevant sensor. How to do this is described
on page 3-11. The log book message is recorded in the log book of the
relevant main sensor (VARiON A -> message code IC5395 or VARiON
N -> message code IC6396).
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+ or Cl- Measured or entered interfering ions 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.
