(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
common R
is 100 . Most RTDs come in a three-

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.
