Specify wiring configuration of RTD device
Description
Use this property to specify the wiring configuration for measuring resistance.
When you create an RTD channel, the wiring configuration is

FourWire
Example
Specify Channel’s RTD Configuration
Specify an RTD channels wiring configuration.
Create a session and add an RTD channel to it.
s = daq.createSession('ni'); ch = addAnalogInputChannel(s,'cDAQ1Mod7',3, 'RTD');
Change the RTDConfiguration
to ThreeWire
.
ch.RTDConfiguration = 'ThreeWire'
