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.
