Operation; Run-In Period; Calibration - ProMinent DULCOTEST CDP 1 1-mA-2 ppm Mode D'emploi

7
7.1
The sensor requires a run-in period before it will display stable readings.
First commissioning:
Re-commissioning:
Membrane-/electrolyte replacement:
7.2
The sensor can be calibrated after the run-in period.
Preconditions • The sensor has been run in (see 7.1 "Run-in Period")
• Constant flow through in-line probe housing assembly
• Constant sample water temperature
• Similar sample water and sensor temperatures (wait approx. 15 min.)

Operation

IMPORTANT
Do not switch off the measuring system during interval
operation! After operation without chlorine dioxide,
running-in periods are to be rockoned with. If required,
switch on metering unit time-delayed! If no chlorine dioxide
is metered for a longer period of time, the sensor must be
disconnected from the power supply and stored dry.

Run-in Period

Calibration

IMPORTANT
• A slope test must be carried out after replacing the
membrane cap or electrolyte.
• Slope tests must be carried out at regular intervals to
ensure correct functioning of the sensor. When used in
bottle washing machines it may be necessary to re-
calibrate the sensor every week or even more frequently.
• Avoid incorrect dosing due to air bubbles in the sample
water. Air bubbles clinging to the sensor membrane can
result in a measured variable that is too low and thus
lead to incorrect dosage.
• Observe applicable national directives for calibration
intervals.
