Indicate location of channel’s shunt resistor
When working with the session-based interface,
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');
ch.ShuntLocation = 'Internal'
ch = Data acquisition analog input current channel 'ai0' on device 'cDAQ1Mod7': ShuntLocation: Internal ShuntResistance: 20 Coupling: DC TerminalConfig: Differential Range: -0.025 to +0.025 A Name: '' ID: 'ai0' Device: [1x1 daq.ni.CompactDAQModule] MeasurementType: 'Current' ADCTimingMode: HighResolution
