1. Plug the BLACK test lead into "COM" jack of the multimeter;
plug the RED test lead into the "V" jack.
2. Set the meter's Function/Range Selector Switch to the
appropriate ACV or DCV position as desired (see Controls
and Indicators, Items 1 and 13).
3. Place the RED test lead onto the positive (+) side of the item
being tested and the BLACK test lead onto the negative (-)
(across the source/load) side of the item. BE CAREFUL not to
touch any energized conductors with any part of your body.
4. Read the results on the display.
B. RESISTANCE MEASUREMENT Ω Ω (OHMS)
Resistance measurements must be made on "de-ener-
gized" (dead) circuits ONLY. Impressing a voltage across
the multimeter's terminals while set to any resistance
range may result in electric shock, instrument damage
and/or damage to equipment under test. MAKE SURE
equipment is completely de-energized before taking any
resistance measurements.
1. Plug the RED test lead into the "Ω Ω " jack of the multimeter;
plug the BLACK test lead into the "COM" jack.
2. Set the meter's Function/Range Selector Switch to the OHM
"Ω Ω " range function (see Controls and Indicators, Item 3).
NOTE: To obtain accurate readings, disconnect at least
one side of the item under test from the circuit or circuit
board before measuring resistance.
3. Place the RED test lead onto one side of the item being test-
ed and the BLACK test lead onto the other side of the item.
(Polarity does not matter when checking resistance).
4. Read the results on the display.
C. DIODE TEST
To avoid electrical shock and/or damage to the multimeter,
ensure the power is removed from the circuit before any
DIODE testing procedure is conducted. Test diodes on de-
energized (dead) circuits only, never on live circuits.
