Zero level calibration
If one or more of the statements that follow are correct, do a zero level calibration before the sensor
is installed.
• The installation location is a dry channel.
• It is not possible to get an accurate level in the flow because the level changes too rapidly.
• It is not possible to get an accurate level in the flow because of physical hazards.
Note: The sensor is factory-calibrated for the specified range and temperature.
