Important:

Read this operators manual thoroughly before using this multimeter. This
manual is intended to provide basic information regarding this multimeter and
to describe common test procedures which can be made with this unit. Many
types of appliance, machinery and other electrical circuit measurements are
not addressed in this manual and should be handled by experienced
service technicians.
WARNING
!
USE EXTREME CAUTION WHEN USING THIS MULTIMETER.
IMPROPER USE OF THIS METER CAN RESULT IN SEVERE DAMAGE TO
PROPERTY, SEVERE PERSONAL INJURY OR DEATH. FOLLOW ALL
INSTRUCTIONS AND SUGGESTIONS IN THIS OPERATORS MANUAL AS
WELL AS OBSERVING NORMAL ELECTRICAL SAFETY PRECAUTIONS. DO
NOT USE THIS MULTIMETER IF YOU ARE UNFAMILIAR WITH ELECTRICAL
CIRCUITS AND PROPER TEST PROCEDURES.

2.1 For Your Safety

1) Use extreme caution when checking electrical circuits.
2) Do not stand in wet or damp work areas when
! WARNING
working with electricity. Wear rubber soled boots or shoes.
3) WARNING Do not apply more voltage or current than the
!
set range of the multimeter will allow.
WARNING
4) ! Do not touch the metal probes of the test leads
when making a measurement.
3
5) ! WARNING Replace worn test leads. Do not use test leads
with broken or tattered insulation.
6) ! WARNING Discharge a capacitor before measuring it.
7) Remove the test leads from the circuit being measured
as soon as the test is completed. Never reset the
function/range switch to another range while the leads
are still in contact with a circuit.
8) Do not measure voltage when the function/range switch
is set on the resistance (ohms) or the current (10 Amp)
settings. Do not measure current when the meter is set
on the resistance range. Never measure AC voltage
when the meter is set on DC voltage or the 10 Amp range.
Setting the meter on the incorrect function may burn out
some of the internal circuitry and may pose a safety hazard.

3. Operating Suggestions

1) Set the function/range switch to the proper position before
making a measurement. When the voltage or current is not
known, it MUST be determined that the capacity of the
selected range will handle the amount of voltage or current
in the circuit (see #3 under "For Your Safety").
2) Avoid placing the meter in areas where vibration, dust
or dirt are present. Do not store the meter in excessively
hot, humid or damp places. This meter is a sensitive
measuring device and should be treated with the same
regard as other electrical and electronic devices.
3) When the meter is not in use, keep the function/range
switch in the OFF position to keep the batteries
from discharging.
4) When disconnecting the test leads from the unit, always
grasp the leads where the input jacks meet the tester
housing. Do not pull the leads out of the jacks by the
insulated wire or transport the tester using the test leads as
a carrying strap.
5) ! WARNING Do not immerse the meter in water or solvents.
To clean the housing use a damp cloth with a minimal
amount of mild soap.
NOTE: With any measurement made by this meter, there will
be some fluctuation of the digital display. This is due to the
meter's sampling method. This unit samples at a rate of 2
times per second, thus the fluctuation of the readout.
