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

to return to the upper-level menu.
