Zero point calibration with
disinfectant-free water
7
If disinfectant-free water (e.g. by switching off the dosing
system) is available, zero point calibration can be performed
with it. To do this, switch off the dosing system and perform
steps 1, 2, 3, 5 and 6. It is necessary to observe the sample
water take-off and dosing delay time here!
8
Open the ball valve on the sample water inlet.
Measurement value calibration
(DPD)
9
After zero point calibration, wait at least 2 minutes.
10
Open the knurled nut on the drain by approximately one turn
and extract a specimen of the sample water.
11
Determine the free chlorine, ozone, chlorine dioxide or
potassium permanganate content, for example, with a
photometer.
12
Select the parameter "Cal. Span" and confirm with "Enter".
13
Enter the determined value with the arrow keys and then press
the "Enter" key to save.
This concludes the calibration.
Please note
In the DPD calibration of the Cl2++ measurement, the calibration
value should be greater than or equal to 25% of the measurement
range.
