Measuring Temperature; Using Thermocouples - Fluke 701 User Manual

Measuring Temperature

Using Thermocouples

The calibrator supports eleven standard
thermocouples, each identified with an alpha
character: C, L, U, E, N, J, K, T, B, R, or S. Table 5
summarizes the ranges and characteristics of the
supported thermocouples.
To measure temperature using a thermocouple,
proceed as follows:
1. Attach the thermocouple leads to the appropriate
TC miniplug, then to the TC jack as shown in
Figure 12. One pin is wider than the other. Do
not try to force a miniplug in the wrong
polarization .
NOTE
If the calibrator and the thermocouple plug
are at different temperatures, wait one
minute or more for the connector
temperature to stabilize after you plug the
connector into the TC jack.
2. If necessary, press M for MEASURE mode.

3. Press tso that the display prompting you to
select the TC type shows.
4. Select the desired TC type using the u or d
followed by e.
5. If necessary, you can change between °C or °F
Temperature Units in s mode as follows:
a. Press s
b. Press the Next Page softkey twice.
c. Use the u and d keys to move the cursor
to the parameter you which to change, then
press e or the Choices softkey to
choose a setting for that parameter.
d. Press u or d to move the cursor to the
desired setting.
e. Press e to go back to the s
display.
Press the Done softkey or s to exit s
f.
mode.
6. If necessary, you can change between ITS-90 or
IPTS-68 Temperature Scale in s mode. The
procedure is the same as steps a through f
above.
