Using Measure Mode

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 R0. The most common R0 is 100 . The calibrator accepts RTD measurement inputs in two-, three-, or four-wire connections, with the three-wire connection the most common. A four-wire configuration provides the highest measurement precision, and two-wire provides the lowest measurement precision.

To measure temperature using an RTD input, proceed as follows:

1.If necessary, press Mfor MEASURE mode.

2.Press Rfor the RTD display. If desired, continue pressing this key to select the desired RTD type.

3.Press Xor Wto select a 2-, 3-, or 4- wire connection.

4.Attach the RTD to input terminals as shown in Figure 11.

If necessary, you can select °C temperature units by pressing F, or °F temperature units by pressing
