Measuring Temperature
Using Thermocouples
The calibrator supports eleven standard
thermocouples, each identified with an alpha
character: E, N, J, K, T, B, R, S, C, L, or U. 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 input/output 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
miniplug into the TC input/output.
2.
If necessary, press
M
for MEASURE mode.
3.
Press
t
. Choose “TC”, then the display
prompts you to select the thermocouple type.
4.
Select the desired thermocouple type using the

softkey twice.
c.
Use the
u
and
d
keys to move the cursor
to the desired parameter. Then press either

display.
f.
Press the Done softkey or

to exit Setup
mode.
6.
If necessary, you can change between
ITS-90
or
