Measuring Temperature
The multimeter uses a type-K (default setting) or a type-J (U1242C only)
temperature probe for measuring temperature. To measure temperature 1 (T1),
set up your multimeter as shown in
.
Probe the test points and read the display. The primary display normally shows
temperature or the message OL (open thermocouple). The open thermocouple
message may be due to a broken (open) probe or because no probe is installed
into the input terminals of the multimeter.
WARNING
Do not connect the thermocouple to electrically live circuits. Doing so will
potentially cause fire or electric shock.
CAUTION
Do not bend the thermocouple leads at sharp angles. Repeated bending
over a period of time can break the leads.
