5 Rinse off the escaped electrolyte with water.
Please note
The membrane cap (E) must be completely screwed (hand-tight)
onto the electrode shaft (B), so that no gap remains between the
two! After a run-in period of about one hour, the membrane sensor
is sufficiently run-in for an initial calibration to take place.
Calibration should be repeated after one day.
Inserting into the flow-through
adapter
1 Insert the membrane sensor through the cover into the flow-
through adapter until it is resting mechanically on the inflow
mating connector and therefore receives a good flow. It may
be necessary to turn the flow-through adapter cover to set it in
the right position relative to the inflow mating connector.
Please note
Remove air bubbles from the membrane by lifting the membrane
sensor. They interfere with the measurement!
2 Connect the measuring signal cable to the measuring device.
Please note
If the measuring sensor is installed this way, it will function reliably
for approx. three to six months.
Storing the membrane sensor
1 Lift elastomer seal (H) and only then screw off the membrane
cap (E).
2 Wash the membrane cap (E) and electrode finger (D) with
clean (distilled) water.
3 Carefully dry the electrode finger (D) with absorbent paper.
4 Leave the membrane cap (E) to dry in a dust-free place.
5 Screw the dry membrane cap (E) loosely onto the electrode
shaft (B).
Please note
The membrane (G) may not touch the gold working electrode (J).
