CAPACITANCE MEASUREMENTS

WARNING: To avoid electric shock, disconnect power to
the unit under test and discharge all capacitors before
taking any capacitance measurements. Remove the
batteries and unplug the line cords.
1. Set the rotary function switch to the Ω CAP
2. Insert the black test lead banana plug into the
negative COM jack.
Insert the red test lead banana plug into the
positive V jack.
3. Press the MODE button to indicate "nF" on
the display.
4. Touch the test leads to the capacitor to be
tested.
5. The test may take up to 3 minutes or more for
large capacitors to charge. Wait until the
readings settle before ending the test.
6. Read the capacitance value in the display
Note: Upon entering the capacitance mode and
with no component connected, the meter will autorange to
the 0.000nF range. This is not a measurement range, but
is used to establish a zero reference.

FREQUENCY/DUTY CYCLE MEASUREMENTS

(ELECTRONIC)
1. Set the rotary function switch to the "Hz %"
position.
2. Press the Hz/% button to indicate "Hz" in the
display.
3. Insert the black lead banana plug into the
negative COM jack and and red test lead
banana plug into the positive Hz jack.
4. Touch the test probe tips to the circuit under
test.
5. Read the frequency on the display.
6. Press the Hz/% button again to indicate "%" on
the display.
7. Read the % of duty cycle on the display.
