one year fromthe dateofpurchase.This warranty does notcover fuses,
disposable batteries, or damage from accident, neglect, misuse,
alteration, contamination, or abnormal conditions of operation or
handling. Resellers are not authorized to extend any other warranty on
our behalf.Toobtainservice during the warrantyperiod, returnthe unitto

THIS WARRANTY IS YOUR ONLY REMEDY. NO OTHER
WARRANTIES, SUCH AS FITNESS FOR A PARTICULAR
PURPOSE, ARE EXPRESSED OR IMPLIED. WE ARE NOT
LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR
CONSEQUENTIAL DAMAGES OR LOSSES, ARISING FROMANY
CAUSE OR THEORY. Since some states or countries do not allow the
exclusion or limitation of an implied warranty or of incidental or
consequentialdamages,thislimitationof liability maynot apply toyou.
WARNING AND PRECAUTIONS
To avoid possible electric shock or personal injury, and to
avoid possible damage to the meter or to the equipment
under test, comply with the follow practices:
Do not use the meter if it is damaged. Before you use the
meter, inspect the case. Pay particular attention to the
insulation surrounding the connectors.
Inspect the test leads for damaged insulation or exposed
metal. Check the test leads for continuity. Replace
damaged test leads before you use the meter.
Do not use the meter if it operates abnormally. Protection
may be impaired. When in doubt, have the meter
serviced.
Do not operate the meter around explosive gas, vapor,
or dust.
Do not apply more than the rated voltage, as marked on
the meter, between terminals or between any terminal
and earth ground.
Before use, verify the meter’s operation by measuring a
known voltage.
When measuring current, turn off circuit power before
connecting the meter in the circuit.
- 3 -
When servicing the meter, use only specified
replacement parts. Do not use the Meter in a manner not
specified by this manual or the safety features of the
Meter may be impaired.
Use with caution when working above 30V ac rms, 42V
ac peak, or 60V dc. Such voltages pose a shock hazard.
When using the probes, keep your fingers behind the
finger guards on the probes.
Connect the common test lead before you connect the
live test lead. When you disconnect test leads,
disconnect the live test lead first.
Remove the test leads from the meter before you open
the battery door.
Do not operate the meter with the battery door or
portions of the cover removed or loosened.
To avoid false readings, which could lead to possible
electric shock or personal injury, replace the batteries as
soon as the low battery indicator (“ ”) appears.

OPERATING INSTRUCTIONS
WARNING
To avoid electrical shock hazard and or damage of
the instrument, do not measure voltages that
might exceed 600V above earth ground.
Before the use of instrument, inspect test leads,
connectors and probes for cracks, breaks, or
crazes in the insulation.
Dangerous voltages may be present at the input
terminals and may not be displayed.
To avoid electrical shock or damage to the Meter
when measuring resistance or continuity in a
circuit, make sure the power to the circuit is
turned off and all capacitors are discharged.
DC & AC VOLTAGE MEASUREMENT
1. Connect red test lead to “VΩmA ” jack, Black lead to
“COM” jack.
2. Set RANGE switch to desired VOLTAGE position, if
the voltage to be measured is not known before hand,
set switch to the highest range and reduce it until
satisfactory reading is obtained.

INDUCED VOLTAGE TEST
1. RANGE switch to desired “NCV” position.
2. The induced voltage sensor above the table is close
to the ac charged body.
3. When the sensor detects the presence of ac voltage,
the buzzer will sound and the display screen will
display the intensity of the corresponding induced
voltage.
MAINTENANCE
Tocleanthe terminals
a)Turnthe MeterOFF and removethe testleads.
b)Shakeout anydirtthatmay be inthe terminals.
c) Soak a new swab with isopropyl alcohol and work around the inside
ofeachinputterminal.
d) Use a new swab to apply a light coat of fine machine oil to the inside
ofeachterminal.
BATTERY REPLACEMENT
1)Battery replacement should only be done after the test leads have
beendisconnectedand powerisoff.
2)Remove the battery cover at the bottom.
3)The meter is powered by two single 1.5V battery.Remove
the old battery from the battery bin at the bottom of the
meter and reload the new battery.And cover the battery
cover.
