Press to change the temperature units between °C or
°F (you must first change the temperature unit to switch
between °C and °F or °F and °C). See “Changing the
temperature unit” on page 117 for more information.

CAUTION
The option to change the temperature unit is locked for certain regions.
Always set the temperature unit display per the official requirements
and in compliance with the National laws of your region.
NOTE
• Shorting the terminal to the COM terminal will display the
temperature at the multimeter’s terminals.
• To change the default thermocouple type from type-K to type-J, see
“Changing the thermocouple type” on page 116 for more information.
NOTE
The bead-type thermocouple probe is suitable for measuring temperatures
from –40 °C to 204 °C (399 °F) in PTFE-compatible environments. 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.
