16. Reinsert electrodes.
17. Reopen the check valve on the sample water inlet.
18. Perform calibration after approximately three hours running-in time.
NOTE: you must calibrate each time the cell sand is replaced. The cali-
bration must be checked after one day. We recommend checking and, if
necessary, replacing the electrodes and diaphragms when replacing the
cell sand (see “Replacing electrolyte, electrodes and porous membranes”).
W2T7957 Three-Electrode Cell Check Electrolyte Level
1. Check whether the electrolyte is filled approx. 3 cm over the water level
(narrowing of the KCL container) and replenish, if necessary.
2. To do this, remove the plug in the upper part of the electrolyte tank
and inject the electrolyte (use the syringe in the accessory set). The
porous membranes in the electrolyte tank form the connection between
the reference electrolytes and the sample water. If the sample water
quality is poor (e.g. high iron content), both porous membranes in the
electrolyte housing should be replaced. The porous membranes should
be white (any coloration is an indication that the porous membranes
are clogged and should be replaced).
3. Calibrate after approximately three hours.
NOTE: The calibration must be checked after one day.
Replacing Electrolyte, Electrodes and Porous Membranes
1. Remove flow block assembly cover.
2. Close the ball valve on the sample water inlet.
3. Open the drain valve and drain the cell body (hold container underneath).
4. Close the drain valve when the cell body is empty.
5. Remove the sensors. Loosen the cable union (hold the cable while
doing this as it may not be allowed to rotate).
6. Loosen the lower cap on the 3 electrode cell.
7. Remove the signal cable.
Replace Electrolyte
8. Unscrew the upper knurled nut on the electrolyte container.
9. Remove the electrolyte tank out of the cell body from below using the
electrode mount.
