Shunt Readings
Shunt resistors simulate a load on the load cell; thus, allowing for calibration. Follow
the steps below in order to utilize the shunt feature.
1. Determine the value of the shunt resistor needed
2. Connect the shunt resistor in the spot labeled ‘RSH’.
3. Press the pushbutton that corresponds to the shunt.
4. While the shunt is enabled and the CSG110 is reading the simulated load, adjust
the span (described above) to the correct output.
Ex. If you are using a 2 mV/V sensor with a 350 Ohm bridge and the default 60.4 kOhm
resistor on the CSG110, then the simulated load would be approximately 72% of R.O.
You can then adjust the span to 7.2 VDC to correlate with this simulated load.
Switch Configurations
To change any of the switch configurations from the default settings, follow the tables
below to set your desired configuration. The figure below shows the default
configuration.
