Incorrect calibration
An error message appears if the
result of the calibration lies out‐
side the specified tolerance
limits. In this case the current
calibration is not carried over.
Check the prerequisites for cali‐
bration and eliminate the error.
Then repeat calibration.
Cleaning and care of pH
and ORP sensors
Please note the separate
instructions supplied with the pH
and ORP sensors for cleaning
and care of pH and ORP sen‐
sors.
After cleaning, the sensor must
be conditioned in 3-molar potas‐
sium chloride solution for 60
minutes before it can be reused
for calibration.
Carry over the result of the calibration
into the controller memory by pressing
.
The controller shows the contin‐
ð
uous display again and operates
with the results of the calibration.

Questions and answers
How do I calibrate measuring channel
To calibrate a measuring channel on a ProMinent diaLog DACb:
1. Select the channel to be calibrated (e.g., Channel 1: Chlorine).
2. Access the [Calibration] menu from the continuous display.
3. Follow the on-screen instructions to perform the calibration.
4. Adjust the value using the appropriate buttons if prompted.
5. Import the calibration result into the controller memory by pressing the confirmation button.
6. The controller will return to the continuous display and use the new calibration values.
If calibration values are outside specified limits, an error message appears, and the calibration is not saved. In that case, check conditions, correct any issues, and repeat the calibration. Each measuring channel must be calibrated separately.
