Step #13: “Zero pressure/Span pressure” sensor calibration
This step is only required for pressure transducers with mV output. For transducers
with 4‐20mA or J1939 outputs calibration is not required, go to Step #14.

WARNING
Make sure the boom is mechanically supported by the cylinder stops to
prevent a sudden fall when the residual hydraulic pressure is released.
To zero the pressure sensors, open the hydraulic lines of both sensors in order to
remove any residual pressure.
The pressure sensor must be electrically connected according to the wiring drawing
supplied for normal operation.
