Step 1 Setup the unit
Click on the button to access the setup interface. The parameter should typically be
set as shown on figure above.
Before a measurement, the operator should set the sensitivity of the sensor used. This sensitivity can
be set manually if it is known. Preferably, the sensor sensibility should be set by using the software
calibration tool and a calibrator. To do so, click on and follow the instructions of the
Sensor Calibration (section 0, p.15).
The level measurement can be made using an external generator or the internal generator (pink or
white noise).
