Units
Specify unit of RTD measurement
Description
Use this property to specify the temperature unit of the analog input channel with RTD measurement type in the session-based interface.
You can specify temperature values as:
Celsius
(Default)Fahrenheit
Kelvin
Rankine
Example
Change RTD Unit
Change the unit of an RTD channel.
Create a session, add an analog input RTD channel, and display channel properties.
s = daq.createSession('ni'); ch = addAnalogInputChannel(s,'cDAQ1Mod7', 0, 'RTD')
ch = Data acquisition analog input RTD channel 'ai0' on device 'cDAQ1Mod7': Units: Celsius RTDType: Unknown RTDConfiguration: Unknown R0: 'Unknown' ExcitationCurrent: 0.0005 ExcitationSource: Internal Coupling: DC TerminalConfig: Differential Range: -200 to +660 Celsius Name: '' ID: 'ai0' Device: [1x1 daq.ni.CompactDAQModule] MeasurementType: 'RTD' ADCTimingMode: HighResolution
