2. Set the function/range switch to "Ω" range.
3. Connect the test leads to the load being measured.
4. Read the results on the display.
NOTE:
a. For resistance measurements >1MΩ, the meter may take a few seconds to stabilize the
reading. This is normal for high-resistance measurements.
b. When the input is not connected, (E.G. the circuit is open) the symbol "OL" will be
displayed as an over range indicator.
c. Before measuring in-circuit resistance, be sure that the circuit being tested 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 test lead to the "VΩ" Jack.
2. Set the function/range switch to "
3. Press the Select Button to select the continuity measurement mode. The "
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. 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 Test Lead to the "VΩ"
Jack. (Note: the polarity of the red test lead is positive "+")
2. Set the function/range switch to "
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 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.

AUTO POWER OFF

If the meter is not in operation for 15 minutes, it will turn off automatically. To turn it on again,
simply rotate the range switch or press any button.
If you press the "HOLD" button to turn the meter back on after it turns off, the automatic power-
off function will be disabled.
