Performing Temperature Measurement
Temperature measurement function is only available for U1212A and U1213A
only.
1
Set the rotary switch to
Ω
.
2
Press
Shift
twice to select temperature measurement.
3
Connect the thermocouple adapter (with the thermocouple probe connected
to it) into input terminals (
red
) and COM (black).
4
Touch the measurement surface (device under test) with the thermocouple
probe and read the display.
NOTE
The bead-type thermocouple probe is suitable for measuring temperatures from
–20 °C to 204 °C in PTFE-compatible environments. Above this temperature
range, the probe may emit toxic gas. Do not immerse this thermocouple probe in
any liquid. For best results, use a thermocouple probe designed for specific
application — an immersion probe for liquid or gel, and an air probe for air
measurement. Observe the following measurement settings:
– Clean the surface to be measured and ensure that the probe is securely
touching the surface. Remember to disable the applied power.
– When measuring above ambient temperatures, move the thermocouple
along the surface until you get the highest temperature reading.
– When measuring below ambient temperatures, move the thermocouple
along the surface until you get the lowest temperature reading.
– Place the clamp meter in the operating environment for at least 1 hour as the
clamp meter is using non-compensation transfer adapter with miniature
thermal probe.
CAUTION
Do not bend the thermocouple leads at sharp angles. Repeated bending
over a period of time can break the leads.
