CALIBRATION
31
Error message: "Prog"
The instrument memory has been corrupted.
Please contact your local RDS distributor.
Error message: "Err"
If the display shows "Err" then there is no pressure signal being received,
indicating either a poor connection in the sensor wiring or a faulty sensor.
Visually inspect the wiring loom and connections first, then if necessary, check
continuity of the sensor lead wires between the "Terminator" screw terminals
labelled “LOAD SENSOR” and the “Weatherpak” connector on the other end of
the load sensor lead. If the wiring is OK then contact your local RDS distributor.
Error Message: “CAL” “Err”
If the “Autocal” routine is not fully completed (i.e. the “Zero” lift and the “LOAD”
lift), the display will flash “
CAL
” and “
Err
”.
The full “Autocal” routine must be carried out again.
Changing loading attachments
If after changing the loading attachment and zeroing the weight, you find that
the weight readings are no longer correct, it is usually because the centre of
gravity of the machine has been slightly altered by the different attachment.
This will affect the load-pressure relationship and therefore the calibration
factor must be adjusted to suit. Perform the weight calibration routine to re-
establish the correct factor.
