Resistance Measurements
1. Insert the black test lead into the negative COM terminal and the red test lead
into the V·
Ω
·CAP·Hz· positive terminal.
2. Set the function switch to the
Ω
position.
3. Touch the test probe tips across the circuit or component under test.
4. Read the resistance on the LCD display.
Capacitance Measurements
WARNING: To avoid electric shock, discharge the capacitor under test before measuring.
1. Set the function switch to the CAP position.
2. Insert the black test lead banana plug into the negative COM jack and the red
test lead banana plug into the V·
Ω
·CAP·Hz· positive jack.
3. Touch the test probe tips across the part under test. If “ dISC ” appears in the
display, remove and discharge the component.
4. Read the capacitance value in the display.
5. The display will indicate the proper decimal point and value.
Note: For very large values of capacitance measurement it can take several minutes
before the final reading stabilizes.
Frequency Measurements
1. Insert the black test lead banana plug into the negative COM jack and the red
test lead banana plug into the V·
Ω
·CAP·Hz· positive jack.
2. Set the function switch to the V Hz Position.
3. Press and hold the MODE button to select the Frequency (Hz) function. “ k Hz ”
will appear in the display.
4. Touch the test probe tips across the part under test.
5. Read the Frequency value on the display.
6. The display will indicate the proper decimal point and value.
7. Press and hold the MODE button again to return to the voltage mode.
