Indicate location of channel’s shunt resistor


When working with the session-based interface, ShuntLocation on the analog input current channel indicates if the shunt resistor is located internally on the device or externally. Values are:

  • 'Internal': when the shunt resistor is located internally.

  • 'External': when the shunt resistor is located externally.

If your device supports an internal shunt resistor, this property is set to Internal by default. If the shunt location is external, you must specify the shunt resistance value.


Specify Shunt Location

Set the shunt location of an analog input current channel.

Create a session and add an analog input current channel.

s = daq.createSession('ni')
ch = addAnalogInputChannel(s,'cDAQ1Mod7',0,'Current');

Set the ShuntLocation to Internal.

ch.ShuntLocation = 'Internal'
ch = 

Data acquisition analog input current channel 'ai0' on device 'cDAQ1Mod7':
