3. Be sure, that the display works in the temperature mode
during the measurement.
At the beginning, set the current to a value of 30 mA. The
magnetic field is off. The current remains nearly constant
during the measurement, but the voltage changes according
to a change in temperature. Set the display in the temperature
mode, now. Start the measurement by activating
the heating coil with the ”on/off”-knob on the backside of
the module.
Determine the change in voltage dependent on the change
in temperature for a temperature range of room temperature
to a maximum of 170°C.
You will receive a typical curve as shown in Fig. 5
