• Therm
- The THERM (thermistor) converts the temperature variation information
into resistance variation information. It is especially sensitive to
temperature.
In this measurement, the multimeter adopts Steinhart-Hart approximate
arithmetic and converts the resistance signal from the temperature sensor
into the related temperature for displaying.
To use the THERM sensor, you need to set the resistance parameter of the
multimeter and select the connection mode.
Click or tap the drop-down list of
Measurement Type to select "Therm".

- Resistance: sets the resistance at temperature 25℃. The available
choices are 2.2 kΩ, 3 kΩ, 5 kΩ, 10 kΩ, and 30 kΩ. By default, it is 2.2
kΩ.
