9. Open the ball valve on the sample water inlet and if necessary the
sample water return line. The cell body fills with sample water once
more. A rotating air bubble does not affect measurement, it disap-
pears on its own.
10. Replace the housing cover and click into place.
After 2 to 3 hours running-in time perform chlorine zero point calibrati-
on. If necessary repeat the chlorine zero point calibration after 24
hours.
Total chlorine sensor:
Replace the electrolyte
Replace the membrane
cap
CAUTION!
Do not touch or damage the reference electrode and keep it clean!
Before unscrewing the membrane cap 3, remove the elastomer seal 5
to allow air into the vent hole 4. Not doing this will cause a vacuum to
occur which will damage the membrane. Do not remove the yellow-
grey layer on the reference electrode 8. Do not move the yellow-grey
layer towards the gold working electrode 7!
1. Open the sensor. Before unscrewing the membrane cap 3, remove
the elastomer seal 5 to allow air into the vent hole 4.
2. Pour away the electrolyte.
3. Clean the reference electrode 8 with distilled water and dry with a
clean paper towel.
4. Fill the membrane cap 3 to the top with the enclosed electrolyte
(special electrolyte for brine application! Refer to the chapter Spare
partes).
1 Counter electrode 5 Elastomer seal
2 Electrode finger 6 O-ring
3 Membrane cap 7 Gold working electrode
4 Vent hole 8 Reference electrode
5. Clean the gold working electrode 7 with the enclosed lapping pa-
per (special abrasive paper). To do this, place the special abrasive
paper on a paper towel. While holding on to a corner of the paper
move the tip of the electrode of the vertically held probe one or two
times over the rough side of the special abrasive paper.
6. Ensure that the elastomer seal 5 completely covers the vent hole.
7. While holding the electrode shaft in a vertical position, screw on the
cap onto the shaft. Surplus electrolyte will escape through the vent
hole 4 in the membrane cap below the elastomer seal. Do not hold
the vent hole 4 or press on the elastomer seal 5! The membrane
cap must be completely screwed to the electrode shaft so that no
gap remains between membrane cap and electrode shaft.
8. Wash away the escaped electrolyte with water.
9. The sensor requires a 1-2 hour run in time before a first calibration
can be performed. The final calibration should be done after 1 day.
