Please see the installation instructions shipped with the selected load weigher.
Weigher Calibration with iControl
1. Connect a multimeter to test points
TP_LW
and
GND
on the ICE-CTP board in the
cartop Box. Adjust trimpot
LW ADJ
until the meter reads the same value noted in step
6 in the calibration procedure.

2. To view load weigher voltages using the iView Virtual Oscilloscope:
• Connect to the controller; display the Virtual Oscilloscope (View > Virtual Oscillo-
scope)
• Select Load Weigher (Raw) for Test point 1
• Observe Load Weigher voltage values on the digital display.
3. To verify the linearity of the load weigher, place weights in the car that represent the fol-
lowing and observe the voltage values:
• Empty car - about 0.0 volts
• 25% of overload weight - about 2.5 volts
• 50% of overload weight - about 5.0 volts
• 75% of overload - about 7.5 volts
• Full load weight - about 8 volts
• Overload weight - about 10 volts
4. On the iView Controller > Configuration > Load Weigher tab:
• Set
Load weighing device type
to
Analog signal.
•
Set
Sensing type
to
Cross head deflection or rope tension sensing.
