5.6 Measuring Resistance Temperature Detector
(RTD)
When using the terminal adapter (model: 99022), tighten the knob by hand.
Do not use a tool or the like. Tightening the knob using a tool or the like may
damage the terminal, resulting in the disability of measurement.
Before storing the instrument in the carrying case, remove the terminal adapter
(model: 99022).
If the instrument is stored in the carrying case while the adapter is attached,
an external force may be applied to the terminal, thus causing damage to the
terminal and resulting in the disability of measurement.

1 Connect the terminals as shown in the gure above.
2 Use the FUNCTION key on the MEASURE side to align
the measurement mark with RTD.
(Resistance temperature detector selection)
3 Use the RANGE key to select a range. (PT100, JPT100)
You can select the temperature scale standard (ITS-90, IPTS-68).
4 The measurement value and unit (°C) appear.
Tip
• For accurate measurement, use the three-wire method.
• About Temperature Scale Standards
You can select from ITS-90 and IPTS-68 in setting mode.
(IPTS-68 appears if IPTS-68 is set.)
For details, refer to “4.6 Generating Resistance Temperature Detector (RTD)
Signals” and “7. Setting Mode.”
