– This may result in uncontrolled metering
– Therefore, the operator should make sure that no subsequent damages can
result from this
CAUTION!
Incorrect metering due to premature ageing of sensor
Possible consequence: Slight or minor injuries. Material damage.
Measure: Do not electrically disconnect the sensor during measuring breaks.
Exception: If there is a break between measurements lasting more than a week and
the proportion of disinfectant in the sample water falls during this period to 0 ppm
then you must electrically disconnect the sensor.
– An extra run in period will be necessary following operation without disinfectant.
Switch on metering equipment with a time delay if necessary.
Run-in period
The sensor requires a specific run in period to display a steady display value.
