measurement mode, and the symbol “ ” will appear
as an indicator.
4) Connect the red test lead to the anode of the diode to
be tested and the black test lead to the cathode.

1) Set the function range switch at the TEMP position.
2) Make sure the polarity of the thermocouple is correct;
put the cold end (free end) of the thermocouple sensor
into the terminal (black to COM jack and red to
“ ” jack).
3) Set the working end (testing end) on or inside the
object under test.
4) The value of the temperature is shown on the display
in degree centigrade (°C).
5) Press the “SELECT” Button,fahrenheit and celsiuscan
