3 Unscrew and remove the sensor cap [H] from the Swansensor
Oxytrace G [A].
4 Empty the remaining electrolyte.
5 Refill the sensor cap with fresh electrolyte.
NOTICE: There is a groove [C] in the thread [B] of the sensor,
where excessive air and electrolyte can escape while screwing
the sensor cap onto the sensor. Hold the sensor in vertical
position, measuring head pointing downwards.
6 Slowly screw the sensor cap onto the sensor to allow the ex-
cess electrolyte to escape without building up too much pres-
sure inside the electrode. Fasten sensor cap tightly.
7 Clean the sensor thoroughly and dry the sensing membrane
with a soft tissue.
8 Switch on power.
9 Let the sensor run-in at air for at least 30 min, better 1 h.
10 Afterwards perform an air calibration.
11 Install the sensor into the flow cell.
12 Select “New Filling” to reset the counter for remaining electro-
lyte, see <Maintenance>/<Service> 3.2.1, p. 71 ).
