6-4. Continuity Test
1) Connect the BLACK test lead to the “COM jack and the RED
to the “INPUT jack (Note: The polarity of the red test lead is
positive “+”).
2) Set the range switch to or range position.
3) Press the “SEL Button to select continuity measurement mode,
and the symbol will appear as an indicator.
4) Connect the test leads across the load to be measured.
5) If the circuit resistance is lower than about 30Ω, the built-in
buzzer will sound.
6-5. Diode Test
1) Connect the BLACK test lead to the “COM jack and the RED
to the “INPUT jack (Note: The polarity of the red test lead is
positive “+”).
2) Set the range switch to or range position.
3) Press the “SELECT Button to select continuity 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.
5) The meter will show the approximate forward voltage of the
diode. If the connections are reversed, “OL will be shown on
the display.
6-6. Measuring Temperature
1) Set the function range switch at the °C or 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).
NOTE:
a) The testing temperature is displayed automatically when the
thermocouple is put into the testing holes.
b) The surrounding temperature is shown when the circuit of the
