Measuring Temperature
Do not bend the thermocouple leads at sharp angles. Repeated bending

over a period of time can result in the leads breaking.
The bead-type thermocouple probe is suitable for measuring temperatures from
–20 °C to 200 °C in PTFE-compatible environments. Do not use the thermocouple
probe beyond the recommended operating range. Do not immerse this
thermocouple probe in any liquid. Use a thermocouple probe designed for each
specific application — an immersion probe for liquid or gel, and an air probe for air
measurement.
Set up the multimeter to measure temperature as shown in
