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.
1. Set the resistance parameter
Press THERM Type and select a desired value from 2.2K (2.2 kΩ), 3K (3 kΩ),
5K (5 kΩ), 10K (10 kΩ) and 30K (30 kΩ).
2. Set the connection type
Press THERM and then press 2WR or 4WR to set the connection mode to
2-wire or 4-wire.
Press
