Do not bend the thermocouple leads at sharp angles. Repeated bending
over a period of time may break the leads.
The bead type thermocouple probe is suitable for making
temperature measurements between –20 °C to 200 °C in
PTFE compatible environments.
Do not use the bead- type thermocouple probe beyond the
recommended operating temperature range. Do not immerse
this thermocouple probe in liquids. For best results, use a
thermocouple probe designed for each application — an
immersion probe for liquid or gel and an air probe for air
measurements.
Set up the multimeter to measure temperature as shown in
Figure 2- 15 or observe the following steps:
1 Press
to select the temperature measurement.
2 Connect the miniture thermal probe into the
non- compensation transfer adapter as shown in
Figure 2- 13.
3 Connect the thermal probe with the adapter into the
meter input terminals as shown in
4 For best performance, place the meter in the operating
environment for at least one hour to stabilize the unit to
environment temperatures.
5 Clean the measurement surface and make sure the probe
is securely touching the surface. Remember to disable the
applied power.
6 When measuring above the ambient temperature, move the
thermocouple along the surface until you get the highest
temperature reading.
7 When measuring below ambient temperature, move the
thermocouple along the surface until you get the lowest
temperature reading.
