Shunt resistors simulate a load on the sensor allowing a calibration to be performed. To simulate a load a resistance value is needed. This resistance value is dependant upon your desired output. Connect the shunt resistor in the spot labeled “RSH” (shown below). Press the push button to engage the shunt and adjust the span and zero (SPAN & ZERO ADJUSTMENT). Shunt resistor values for specific outputs can be calculated using our shunt calculator or taken from the calibration certificate if the amplifier was shipped as a system in conjunction with a sensor.

NOTE: It is not necessary to open the CSG110 to activate the shunt feature, simply press the button through the cover in the location marked 'SHUNT'

Shunt Resistor Location

The shunt resistor is attached in the location marked 'RSH' (shown below). To change the resistance value simply solder your desired resistor into the 'RSH' location.
