Barrier
(2)Press the trigger to open the transformer jaws
and clamp onto a conductor. The most
accurate reading will be obtained by keeping
the conductor at the center of the transformer
jaws.
(3)Read the display.
4-3 AC Voltage Measurement
WARNING
¡ Never use the instrument on a circuit above
600Vrms AC. Measurement on circuits above
this voltage to the instrument or equipment
under test.
¡ Keep your fingers and hands behind the
batteries during measurement.
¡ Do not operate the range switch during a
measurement.
¡ Do not open the battery cover when making
measurement.
(1)Set the range switch to 200V or 600V.
(2)Insert the red plug of the test lead into the V/Ω
terminal and the black plug into the COM
terminal.
(3)Touch the tips of the test leads to the circuit
under test.
(4)Read the display.
4-4 Resistance Measurements and Continuity Check
WARNING
¡ To avoid possible electrical shock and
instrument damage, make sure that a circuit to
be rested is de energized.
¡ Keep your fingers and hands behind the
barrier during measurement.
¡ Do not operate the range switch during a
measurement.
¡ Do not open the battery cover when making
measurement.
(1) Set the range switch to 200Ω.
(2) Insert the red plug of the test lead into the V/Ω
terminal and the black plug into the COM
terminal . With the test leads open, the display
should show “1”on the highest digit(over
range condition)
(3) Short the test leads. The display should read
nearly 0 and the beeper should sound. (Teas
lead have a resistance of about 0.2Ω)

DANGER
¡ Never make measurement on the circuit in which
electrical potential to ground over 600V exists.
¡ Do not attempt to make measurement in the
presence of flammable gasses. Otherwise,
the use of the instrument may cause
sparking, which can lead to an explosion.
¡ Transformer jaw tips are designed not to
short the circuit under test. If equipment
under test has exposed conductive parts,
however, extra precaution should be taken to
minimize the possibility of shorting.
¡ Never attempt to use the instrument if its
surface or your hand is wet . Otherwise, you
may get electrical shock.
¡ Never open the Bottom case and Battery
cover during a measurement.
(4)Connect the leads to the circuit to be tested and
read the display.The beeper sounds below
about 30Ω.
4-5 How to Use Data Hold Function
On all ranges, you can hold a reading on the
display using Data Hold function.
(1)While making measurement, press the Data
Hold switch. The last reading remains held on
the display, with a Hold “
”symbol shown
on the display.
(2)Press the Data Hold switch again to exit from
Data Hold function.
WARNING
¡ To avoid electric shock hazard, make sure to
set the range switch to “OFF”and remove
the test leads from the instrument before
try ng
to replace battery.
If symbol“B”appears on the display, replace the
battery as follows.
(1)Remove test leads from the instrument and set
the range switch to OFF .
(2)Unscrew and remove the battery compartment
cover.
(3)Replace the battery with a new 9V battery,
Type 1604,PP3, 6F22 or equivalent, observing
correct polarity.
(4)Screw the battery compartment cover.
Model 8004 and 8008 (Multi-Tran) extend the
existing current measuring range and the
maximum conductor size.
(1)Set the range switch to 200A or 600A
(2)Clamp a Multi-Tran on a conductor to be tested.
(3)Clamp KEW SNAP 2017 or 2027 on the pick-
up coil of the Multi-Tran.
(4)Read the display and multiply the reading by
10.
WARNING
¡ Never attempt to make any measurement if the
instrument has any structural abnormality such
as cracked case and exposed metal part.
¡ Do not turn the range switch with rest leads
connected to the instrument.
¡ Do not install substitute parts or make any
modification to the instrument. Return the
instrument to the distributor from whom you
purchased this instrument for repair or re-
calibration.
¡ Always switch off the instrument before
opening the battery compartment cover for
battery replacement.
CAUTION
¡ Always make sure to set the Range switch to
the appropriate position before making
measurement.
¡ Always make sure to insert the plug of each
lead fully into the appropriate terminal on the
instrument.
¡ Be sure to set the Range switch to“OFF”
position after use. When the instrument will not
be in use for a long period, place it in storage
after removing the batteries.
¡ Do not expose the instrument to the direct sun,
high temperature and humidity or dewfall.
¡ Use a damp cloth and detergent for cleaning
the instrument. Do not use abrasives solvents.
○Measurement categories (Over-voltage
categories)
To ensure safe operation of measuring
instruments, IEC61010 establishes safety
standards for various electrical environments,
categorized as CAT I to CAT IV, and called
measurement categories. These are defined as
indicated on the next.
CAT.Ⅰ: Secondary electrical circuits connected to
an AC electrical outlet through a transformer
or similar device.
CAT.Ⅱ: Primary electrical circuits of equipment
connected to an AC electrical outlet by a
power cord.
CAT.Ⅲ: Primary electrical circuits of the equipment
connected directly to the distribution panel,
and feeders from the distribution panel to
outlets.
CAT.Ⅳ: The circuit from the service drop to the
service entrance, and to the power meter and
primary over-current protection device
(distribution panel).
¡ Designed to CAT. Ⅲ 600V and pollution degree
2 specified by the international safety standard,
IEC 61010-1.
¡ Tear-drop-shaped jaws for ease of use in
crowded cable areas and other tight places.
¡ Data Hold function.
¡ Wide frequency range from 40Hz to 1kHz.
¡ KEW SNAP 2027 is a true RMS Type that
permits most accurate measurements
independent of waveforms.
