7.4.5 Procedure for calibrating the ultrasound probe model ZWS-70/CI/QS (code 3289173)
Before being assembled the probe must be calibrated in accordance with the following sequence:
1.
electrically connect the sensor (following the electric diagram shown below);
2.
keep the sensor button pressed down until the two LED (green and yellow lights) flash together;
3.
position it in front of the minimum absolute level to be read, entering the height by releasing the button (the two LEDs
display a fixed light);
4.
press the button for 3 or 4 seconds (the probe has acquired the Minimum absolute level);
5.
keep the sensor button pressed down until the two LED (green and yellow lights) flash together;
6.
position it in front of the maximum absolute level to be read, entering the height by releasing the button (the two LEDs have
a fixed light);
7.
press the button for 3 or 4 seconds (the probe has acquired the Maximum absolute level);
8.
In this way the sensor is calibrated.
N.B.:
green Led on indicates that the probe is supplied. Yellow Led on indicates operating mode for reading.
We attach a table with the calibration parameters for the ultrasound probe, for 30 and 100 kg tanks.

N.B.
: In the
30 kg pump tank at the minimum absolute level there is still a reserve of 7 kg
.
In the 100 kg pump tank at the minimum absolute level there is still a reserve of 15 kg.
Green LED:
status indicator.
Signals that the sensor is powered.
Yellow LED:
function indicator.
Report the output status (On/Off).
