CAUTION
Always set the temperature unit display per the official requirements
and in compliance with the national laws of your region.
NOTE
The bead-type thermocouple probe is suitable for measuring temperatures
from –40 °C to 204 °C (399 °F) in Teflon-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 clamp meter in the operating environment for at least 1 hour
as the clamp meter is using a non-compensation transfer adapter with
miniature thermal probe.
