Zero angle calibration:
Ensure the correct side of boom setting has been made before setting the zero datum, if
the side of boom setting is changed then the zero setting must be repeated.
1)
Use
“
”
or
“
”
to choose “Zero” and press
“
”
.
2)
Boom down to zero degrees (main boom horizontal) using a precision angle
measure to accurately establish the true angle of the base boom section. The
angle is displayed in degrees and the sensor value is in bits. This value must be
above 100 bits. If smaller, turn the sensor to increase the value.
3)
Press
“
”
to edit the angle value using
“
”
or
“
”.
4)
Press
“
”
again to confirm the zero.
5)
Press
Escape
to return to the main calibration menu.
The boom angle need not be zero but it’s true value must be accurately known and
entered as described.
3.2 Step #10: “Zero sensor/Span sensor” length sensor calibration
Warning:
The system does not store the ZERO LENGTH into permanent memory until
the SPAN LENGTH calibration has been completed. If a ZERO LENGTH calibration is
done, then a SPAN LENGTH calibration must also be done.
Zero extension calibration:
1)
Use
“
”
or
“
”
to choose “Select sensors” and press
“
”
.
2)
Use
“
”
or
“
