DIODE TEST
1. Set the function switch to the green Ω CAP
position.
2. Insert the black test lead banana plug into the
negative COM jack and the red test lead
banana plug into the positive V jack.
3. Press the MODE button to indicate“ “ and “ V ”
on the display.
4. Touch the test probes to the diode under test.
Forward voltage will typically indicate 0.400 to
0.700V. Reverse voltage will indicate “
OL ”.
Shorted devices will indicate near 0V and an
open device will indicate “
OL
” in both polarities.
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 green Ω
CAP position.
2. Insert the black test lead banana plug into the
negative COM jack.
3. Insert the red test lead banana plug into the
positive V jack.
4. Press the
MODE
button to indicate “
F
”
5. Touch the test leads to the capacitor to be
tested.
