2 Making Measurements
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, the
probe may emit a toxic gas. Do not immerse this thermo-
couple 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.
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 the 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 a quick measurement, use the 0 °C compensation to
see the temperature variation of the thermocouple sensor.
The 0 °C compensation assists in measuring the relative
temperature immediately.
1 Turn the rotary switch to TEMP position.
2 Press to select the temperature measurement.
Do not bend the thermocouple leads at sharp angles. Repeated bending
over a period of time may break the leads.
