Change of load cells
In order to change the load cell you have to do the following:
Switch off power on the machine
-
- loosen the screw at the cross bar
- mount new load cell with the screw at the cross bar
- put load cell plug into the connector at the back side of the machine
- Switch on the machine again and wait to the end of the self-test procedure
- press "5"
- type Password: "09122"
- save old parameters on a piece of paper and type the new values
set new parameter for ‘Load cell’ e.g.: 2000 [N]
set new parameter for ‘mV/V’
(load cell sensitivity) e.g.: 3.165 [ mV/N]
set new parameter for ‘Cal’ (calibration factor) to "1"
Set calibration factor with weight
Put a calibration weight at the load cell, e.g. 10 kg = 98.0665 N (**
The display should show a similar value
E.g. the display shows 95.6 N the calibration factor must be
increased:
From 1 to 1.03745 (use calculator)
Check the changes with the weight again!
** (this is dependent to your location and valid for 45° northern /
e.g. north pole 98.32 N / at the Equator 97.80 N
Mounting procedure of Load Cell
Caution!
Small type of load cells can easily be deformed especially by
torsion forces.
Never put torsion forces on the Load cell while tightening or
loosening probes and clamps
