5.4 Measuring Thermocouple (TC)
5.4 Measuring Thermocouple (TC)
CAUTION
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 figure above.
2
Use the FUNCTION key on the MEASURE side to align
the
measurement mark with TC. (Thermocouple selection)
3
Use the RANGE key to select a thermocouple type.
(K, E, J, T, N, L, U, R, S, B)
4
The measurement value and unit (°C) appear.
Tip
• When there is an overrange or measurement is not possible, “------” appears.
• If the operating environment changes suddenly, wait to stabilize before beginning
measurement.
• It may take a while for the temperature of the terminal parts to stabilize after a
terminal adapter is attached or a thermocouple is connected.
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."
