Measuring Temperature
The bead type thermocouple probe is suitable for making
temperature measurements between –20 °C to 200 °C in
Teflon compatible environments. Above this temperature,
probes may emit toxic gas. Do not immerse this thermocou-
ple probe in liquids. For best results, use a thermocouple
probe designed for each application — an immersion probe
for liquid or gel, an air probe for air measurements. Observe
the following measuring techniques:
•
Clean the measurement surface and make sure the probe
is securely touching the surface. Remember to disable the
applied power.
•
When measuring above ambient temperature, move the
thermocouple along the surface until you get the highest
temperature reading.
•
When measuring below ambient temperature, move the
thermocouple along the surface until you get the lowest
temperature reading.
•
Place the meter in the operating environment for at least
1 hour as using non- compensation transfer adaptor with
miniature thermal probe.
•
For quick measurement, use the 0 °C compensation to see
the temperature variation of the thermocouple sensor. The
0 °C compensation assists you in measuring relative
temperature immediately.

Do not bend the thermocouple leads at sharp angles. Repeated bending
over a period of time can break leads.
