Set the damping (averaging) to 10–30 seconds to prevent "jitter" in the readings caused by surface ripples. 5. Troubleshooting Common Issues
Define the maximum head height corresponding to a 20mA output.
Often caused by electrical interference. Ensure the transducer cable is not run in the same conduit as high-voltage power lines.
Uses a shielded coaxial or twisted-pair cable. Ensure the shield is grounded at the controller end only to prevent ground loops.
Select between Metric (m³/hr) or Imperial (MGD/GPM).
To calibrate the Model 606 without the original paper manual, follow these verified steps via the keypad:
Choose the type of flume or weir you are using (e.g., Parshall Flume, V-Notch Weir).
This is the distance from the transducer face to the zero-level point (the bottom of the flume or the crest of the weir).
