Zero Flow" Point Calibration - Burkert 8041 Manuel Utilisateur

- Slow filtering allows the smoothing out of strong variations in the flow (for example,
fluid containing air bubbles)
- Fast filtering allows the smoothing out of weak variations in the flow.

3.4 "ZERO FLOW" POINT CALIBRATION

Before using the sensor for the first time, its "zero flow"
point must be calibrated.
- Fill the pipe with the fluid and then stop the flow.
- At first commissionning, immerse the sensor in
fluid for 24 hours before calibration (only 1 hour
after maintenance)
- Ensure that there are no air bubbles in the pipe
and that the fluid is immobile before commencing
the calibration
- Check whether the green led flashes once and the red
led is off (Readout mode). If not, refer to § 3.1
- Press and hold the push-button: after 2 seconds,
the red led lights up (Configuration mode) and the
bargraph shows the features "zero flow point
calibration" and "full scale calibration" alternately.
