Resistance value of channel's shunt resistor
When working with the session-based interface, the analog input
indicates resistance in ohms. This value is automatically set if the
shunt resistor is located internally on the device and is read only.
Note: Before starting an analog output channel with an external shunt resistor, specify the shunt resistance value.
Set the shunt resistance 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 = 'External'; ch.ShuntResistance = 20
ch = Data acquisition analog input current channel 'ai0' on device 'cDAQ1Mod7': ShuntLocation: External 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
