34.Press 3 2 0 buttons and then press ENTER function button. “NUM” will dis- appear and “32.0 °F” will appear, not blinking. The voltmeter should read 0.000 mV.
35.Press the SENSOR SELECT function button. The sensor type will change to type D. A “d” will appear momentarily in the center of the display. “32.0” will then appear in the center of the display and both the “T” and “R” will appear along the top row of the display. The voltmeter should read 0.000 mV.
36.Press the SENSOR SELECT function button. The sensor type will change to type K. The “T” and the “R” will disappear from the display and a “K” will appear on the display. The voltmeter should read 0.000 mV.
