Shunt is used to simulate a load on the sensor by using
an internal resistor labeled ‘RSH’ on the CSG110 circuit
board.
The resistor will be connected to the –Excitation and
–Signal of the sensor when the shunt button is pressed.
The internal resistor can be removed and replaced.
To perform a shunt, press the white SHUNT button with no
load on the load cell.
Calibrating using Shunt:
1. The Shunt can be used in calibration by adjusting the
Span Potentiometer while holding the shunt button.
2. Adjust the output voltage from the CSG110 until the
output is as close to the appropriate value for the
shunt.

The online Shunt calculator on the FUTEK website
can be used to calculate an estimated result from
a shunt resistance, or to calculate a resistance
needed for a certain sensor output value when
shunted. http://www.futek.com/shuntcalc.aspx
