Frequently Answers and Questions

How do I calibrate the dissolved oxygen probe?
You can calibrate the probe automatically or manually by entering a reference value. The manual calibration requires a reference value ≥ 2 % of the measurement range. Refer to the 'Calibrating the probe for dissolved oxygen' section in the manual for detailed instructions.
What are the different control modes available for the DULCOMETER D1C?
The D1C offers two control modes: proportional control and PID control. Choose the control mode based on your application requirements and the desired response time.
How do I set up the timer relay function?
You can configure the timer relay to activate for a specific duration based on the cycle time and 't on' value. The 't on' value determines the relay activation time within the cycle. Refer to the 'Timer Relay' section for detailed settings.
How do I adjust the measuring range for the dissolved oxygen probe?
You can adjust the measuring range according to your application needs. However, note that changing the range will reset the setpoints and limit values, so you need to reconfigure them.
