TESTING PROCEDURES
A. AC/DC VOLTAGE MEASUREMENT
WARNING
To avoid possible electric shock, instrument
damage and/or equipment damage, DO NOT attempt
to measure voltages ABOVE 600V AC/DC or take
measurements if the voltage is unknown. 600V
AC/DC between the COM and V jacks is the
maximum voltage that this instrument is designed
to measure. The "COM" terminal potential should
not exceed 300V AC/DC measured to ground.
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 appro-priate ACV or
DCV position as desired
(see Controls and
Indicators, Items 1 and 2).
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 W (OHMS)
WARNING
Resistance measurements must be made on "de-
energized" (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.
