ORP sensor calibration
The ORP sensor cannot be calibrated. Only an
[OFFSET] deviation of magnitude ± 40 mV can be
set and thus compensated. If the ORP sensor
deviates by more than ± 40 mV from the reference
value, then it must be checked in accordance with
the requirements of the sensor operating instruc‐
tions.
Measuring and control behaviour of the controller
during calibration
During calibration the actuating outputs are deacti‐
vated. Exception: a basic load or a manual control
variable has been set. This remains active. The
measured value output [standard signal output mA]
is frozen, corresponding to its settings in the mA
output menu.
When calibration/testing has been completed suc‐
cessfully, all of the error checks relating to the
measured value are restarted. The controller saves
all the determined data for zero point and slope
upon a successful calibration.
Buffer used
Dispose of the used buffer solution. For more infor‐
mation: refer to the buffer solution safety data
sheet.
You need one test container with a buffer solution for calibration.

Do you have a question about the DULCOMETER diaLog DACb and is the answer not in the manual?
Questions and answers
I need to recalibrate my prominent DiaLog DACb are there written instructions I can use
To recalibrate the ProMinent diaLog DACb, follow these steps:
1. Access the calibration function via the controller menu.
2. Use the arrow keys to navigate through the options.
3. Select the appropriate channel and parameter (e.g., Chlorine).
4. Adjust the slope (e.g., 5.99 mA/ppm) and zero point (e.g., 4.00 mA) as needed.
5. Confirm and save the new calibration values.
Ensure the calibration log book is active to store the changes.
