b. When the input is not connected, i.e. at open circuit, the symbol “OL” will be displayed as
an over range indicator.
c. Before measuring in-circuit resistance, be sure that the circuit under test has all power
removed and all capacitors are fully discharged.
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 “
” position
3. Press the “Select” 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.
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 “
” 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.
Capacitance Measurement
1. Connect the black test lead to the COM jack and the red to the “INPUT” jack.
2. Set the range switch to “
”position
3. Press the “Select” Button to select continuity measurement mode, and the symbol “mF”
will appear as an indicator.
4. Connect test leads across the capacitor under measure and be sure the polarity of
connection is observed.
Note:
a. When the capacitance under measure is above 100uF, it needs at least 10 seconds to
make readings stable.
Measuring Temperature
1. Set the range switch to “
℃
” or “
℉
” range.
2. Insert the black (or “-“) plug of the K type thermocouple to the “COM” jack, and the red
(or “+”) plug to the “INPUT” jack.
3. Carefully touch the end of the thermocouple to the object to be measured.
4. The results will be displayed after several moments.
Measuring Frequency/Duty Cycle
1. Connect the black test lead to the COM jack and the red to the “INPUT” jack.
2. Set the range switch to “Hz/Duty Cycle” range.
3. Press the “Select” Button to select “Hz” or “duty cycle” mode
