5.4.3 Membrane sensor calibration
Calibration is nearly identical for all membrane sensors. The
difference lies in the fact that some of the chemicals are measured
manually with a photometer and others with a colour meter.
A 1-point calibration is available to calibrate the total chlorine
measurement and the combined chlorine measurement.
Either the total chlorine or the combined chlorine must be
calibrated.
For the selective ozone, chlorine dioxide and free chlorine
measurements, 1-point or 2-point can be selected in the
"Calibration mode" calibration menu. 2-point calibration provides
the option to compensate for possible measuring cell zero point
offsets.
Total chlorine 1 Open the knurled nut on the drain by approximately two turns
and extract a specimen of the sample water.
2 Determine the total chlorine content with a comparative device
(e.g. photometer).
3 Starting from the basic display in the main menu select the
"Calibration" menu.
4 Select the menu item "Cl-sat" for the measurement you wish to
perform.
Select the parameter "Cal. total" and confirm with "Enter".
5 Use the arrow keys to enter the determined value.
6 Save the value by pressing "Enter".
This concludes the total chlorine calibration.
Combined chlorine (optional) 1 Determine the values for free chlorine and total chlorine as
described under "Total chlorine".
2 Determine the value for combined chlorine:
Total chlorine minus free chlorine.
3 Enter the determined value as described under "Total chlorine"
with the arrow keys under the parameter "Cal. combined".
4 Confirm the entry.
This concludes the combined chlorine calibration.
