Making Measurements 2
Measuring Temperature
U1271A/U1272A User’s Guide 91
The bead- type thermocouple probe is suitable for measuring
temperatures from –40 °C to 204 °C (399 °F) 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 each specific application —
an immersion probe for liquid or gel, and an air probe for
air measurement.
Observe the following measurement techniques:
• 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 multimeter in the operating environment for at
least 1 hour as the multimeter is using a
non- compensation transfer adapter with miniature
thermal probe.
• For quick measurement, use the compensation to view
the temperature variation of the thermocouple sensor. The
compensation assists you in measuring relative
temperature immediately.
