3.1 Zero-setting the pressure signals
NOTE: The only thing adjustable for the pressure transducers is the zero point, which is the signal the
transducer outputs when there is no (zero) pressure sensed.
Ensure there is no pressure in the hydraulic line when
disconnecting the hoses from pressure transducers!
The display shows which transducer (piston-side, rod-side or force) is being zeroed and a horizontal
dial marks the present pressure (or force) difference in %.
NOTE: there are two
calibration screens: for piston and for rod transducer.
NOTE: The operating range for zero-setting this value is from -1% to +1%.
Press and release the “AUTO >CAL<” key multiple times until the zero-setting starts.
The indicator line must move to zero on the dial, otherwise the zero-setting of this value is not
correct!
▼ Zero point adjustment, pressure piston side:
leave the service menu
