Temperature Calibrator
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 Ω. 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 M for MEASURE mode.
2.
Press R for the RTD display. If desired, continue
pressing this key to select the desired RTD type.
3.
Press X or W to 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
D
