How can multimeter measure temperature?

Click For Summary
SUMMARY

The multimeter discussed is equipped with a temperature measurement function that operates through the connection of a thermocouple. It measures temperature by interpreting millivolt signals generated by the thermocouple, applying a specific scaling factor to convert these signals into temperature readings. This method is effective for measuring the temperature of various materials, including insulating materials, not just metals.

PREREQUISITES
  • Understanding of thermocouples and their operation
  • Knowledge of millivolt signal interpretation
  • Familiarity with scaling factors in measurement
  • Basic principles of temperature measurement
NEXT STEPS
  • Research different types of thermocouples and their applications
  • Learn about millivolt measurement techniques
  • Explore scaling factors used in temperature conversion
  • Investigate the limitations of multimeter temperature measurements
USEFUL FOR

Electronics technicians, engineers, and anyone interested in temperature measurement techniques using multimeters.

The multimeter in our lab has temperature measurement function. I am wondering how it works. Can it measure temperature of insulating materials or it just work for metal?

You connect a thermocouple. Temperature is then a millivolt measurement with a scaling factor
