SAFETY PRECAUTIONS/
This Digital Multimeter is intended for INDOOR USE ONLY.
•
Pay close attention to
•
meter's case. These warnings, as well as all warnings and precautions used
through out this manual, must be followed to avoid electric shock and/or per-
sonal injury.
The RESPONSIBLE PARTY shall be made aware that, if the equipment is
•
used in a manner not specified by the manufacturer, the protection provided
by the equipment may be impaired.
To prevent electrical shock and/or damage to the tester or the equipment under
test, observe the following safety precautions:
DO NOT apply more than the rated voltage, as marked on the meter,
•
between terminals or between any terminal and earth ground.
Use caution when working above 30V AC rms, 42 V peak, or 60 V DC. Such
•
voltages pose a shock hazard.
To avoid false readings that could lead to possible electric shock or personal
•
injury, replace the batteries as soon as the low battery indicator
Use ONLY those test leads or probes provided with the meter. DO NOT use third-
•
party test leads or probes.
Always inspect the multimeter, test leads and any other accessories for damage
•
prior to every use. If any damage is found, do not use tester until repairs are done.
Always consider electrical and electronic equipment to be energized (live).
•
Never assume any equipment is de-energized.
Never ground yourself when taking electrical measurements. Isolate yourself
•
from ground by using dry rubber insulating mats to cover all exposed/ground-
ed metal. Stand on rubber mats and wear dry clothing.

TESTING PROCEDURES
A. AC/DC VOLTAGE MEASUREMENT
To avoid possible electric shock, instrument damage and/or equipment
damage, DO NOT attempt to measure voltages ABOVE 500V AC/DC or
take measurements if the voltage is unknown. 500V 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 appropriate ACV or
DCV position as desired.
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.
