Maintenance
Maintenance frequency depends strongly on the water quality. The
AMI Oxytrace QED is designed for determination of low level of dis-
solved oxygen in high purity water.
It is not suitable for the measurement of dissolved oxygen in waste
water.

*A change of membrane and electrolyte is recommended:
 if indicated in the maintenance list (remaining amount <10%)
 if the response of the sensor is slow
 if the sensor can not be calibrated any more and/or the instru-
ment shows a corresponding error message
 if the sensor signal is very unstable.

Stop of Operation for Maintenance

1 Shut off power of the instrument.
2 Stop sample flow by closing the flow regulating valve.
Check sample flow.
If necessary, perform an air calibration.
Clean Oxytrace G membrane with a soft tissue,
see Maintenance of the Oxygen Sensor, p.
Clean faraday electrode, see
Faraday electrode, p. 45
If necessary, replace filling electrolyte.
If the sensor is exposed to air
frequently and during long time intervals, the
electrolyte and membrane may have to be
changed earlier (see below*).
Clean flow cell and flow meter, if dirty.
Replace Swansensor Oxytrace G membrane by
using a new, pre filled sensor cap.
