Chapter 1 Taking Measurements with the NI 4050
© National Instruments Corporation 1-9 NI 4050 User Manual
Measure Temperature
You can measure temperature using common temperature transducers such
as resistive temperature devices (RTD) and thermistors. You can measure
transducers in the 2-wire resistance mode, as shown in Figure 1-8.
Although the soft front panel does not support temperature measurements,
you can convert and scale the transducer value to temperature
programmatically through software.
Note
The NI 4050 for PCMCIA does not support 4-wire resistance measurements. To
avoid measurement errors due to resistance offset, before doing resistance measurements,
measure the resistance to your loads.
