Making Measurements
Performing Temperature Measurement
Temperature measurement function is only available for U1212A and U1213A
only.
The bead-type thermocouple probe is suitable for measuring temperatures from
NOTE
–20 °C to 204 °C 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 specific
application — an immersion probe for liquid or gel, and an air probe for air
measurement. Observe the following measurement settings:
– Clean the surface to be measured and ensure that the probe is securely
– When measuring above ambient temperatures, move the thermocouple
– When measuring below ambient temperatures, move the thermocouple
– Place the clamp meter in the operating environment for at least 1 hour as the
Do not bend the thermocouple leads at sharp angles. Repeated bending
