8.3 Programming
8.3.1 Setting the full scale
Before starting spraying, the control box needs some machine values, which are essential to data
correct display during machine operation:
Pressure transducer full-scale value (0,1 ÷ 999,9 - EU: bar - US: psi).
1) After having been turned ON, the device displays the instantaneous pressure value.
2) To modify the value, keep the keys pressed simultaneously until the “SET” screen appears.
3) Set the full-scale value of the pressure transducer using the [TOT] key to increase it and the [RESET] key
to decrease it; keep the keys pressed to enable quick-modifi cation.
4) To confi rm the setting, keep the keys pressed simultaneously until the “SAVE” screen appears.
8.4 Use
8.4.1 Displaying data
The following parameters can be displayed during operation:
Instantaneous pressure = 0,0 ÷ 999,9 (EU: bar - US: psi).
8.4.2 Adjusting the value of 0
After having turned ON the device, the measured pressure value is displayed, preceded by informa-
tion regarding the software version and unit of measure.
If the device displays a value different from 0 when there is no pressure in the circuit, it will be
necessary to adjust the 0.
1) Turn ON the device, the data regarding the instantaneous pressure is displayed after showing the set unit
of measure.
2) Press the [RESET] key until “RST” appears.
3) The reset value of the instantaneous pressure is displayed.
