Measuring Temperature
Using Thermocouples
The Calibrator supports twelve standard thermocouples,
including types E, N, J, K, T, B, R, S, L, XK, BP, and 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 10.
W
Caution
One thermocouple pin is wider than the other. To
avoid possible damage to Calibrator or to
equipment under test 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
plugging the miniplug into the TC input/output.
2.
If necessary, press
M
for MEASURE mode.
3.
Press
T
for the TC display. Continue pressing this
key to select the desired thermocouple type.
If necessary, toggle between °C or °F temperature
units by pressing
D
.
