U1253A User's and Service Guide
Do not bend the thermocouple leads at sharp angles. Repeated
bending over a period of time can break the leads.
The bead- type thermocouple probe is suitable for measuring
temperatures from –20 °C to 204 °C in Teflon- 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 0 °C compensation to
view the temperature variation of the thermocouple
sensor. The 0 °C compensation assists you in measuring
relative temperature immediately.
