Do not bend the thermocouple leads at sharp angles. Repeated bending over a period of time may break the leads.
The bead type thermocouple probe is suitable for making temperature measurements between
Do not use the bead- type thermocouple probe beyond the recommended operating temperature range. Do not immerse this thermocouple probe in liquids. For best results, use a thermocouple probe designed for each application — an immersion probe for liquid or gel and an air probe for air measurements.
Set up the multimeter to measure temperature as shown in Figure 2- 15 or observe the following steps:
1Press 
to select the temperature measurement.
2Connect the miniture thermal probe into the non- compensation transfer adaptor as shown in Figure 2- 13.
3Connect the thermal probe with the adapter into the meter input terminals as shown in Figure 2- 14.
4For best performance, place the meter in the operating environment for at least one hour to stabilize the unit to environment temperatures.
5Clean the measurement surface and make sure the probe is securely touching the surface. Remember to disable the applied power.
6When measuring above the ambient temperature, move the thermocouple along the surface until you get the highest temperature reading.
7When measuring below ambient temperature, move the thermocouple along the surface until you get the lowest temperature reading.
