If you suspect a sensor error or problem with a sensor, compare the indicated physical value of the
sensor on the display screen with the real value, i.e. length, angle, etc.
The voltages given are internal calculation values only; you will not be able to actually measure them
anywhere on the electronics! Typical values to be expected are:
Pressure transducers (piston and rod), 500mV @ 0 PSI; 4500mV @ maximum PSI
Length sensor, 500mV @ retracted boom length; voltage extended depends on the various
boom lengths.
Angle sensor, 4500mV at 0
; 2500mV at 45
; or 500mV at 90
Please refer to table below for more values.
