Using Resistance-Temperature Detectors (Rtds); Rtd Types Accepted - Fluke 744 User Manual

Using Resistance-Temperature Detectors
(RTDs)
The calibrator accepts RTD types shown in Table 6.
RTDs are characterized by their resistance at 0 °C
(32 °F), which is called the "ice point" or R
most common R is 100 . Most RTDs come in a

three-terminal configuration. The calibrator accepts
RTD measurement inputs in two-, three-, or four-wire
connections as shown in Figure 15. A four-wire
configuration provides the highest measurement
precision, and two-wire provides the lowest
measurement precision.
