safety rules which must be observed by the user to ensure safe
operation of the instrument and retain it in safe condition. Therefore,
read through these operating instructions before using the
instrument.
● Read through and understand the instructions contained in this
manual before using the instrument.
● Keep the manual at hand to enable quick reference whenever
necessary.
● The instrument is to be used only in its intended applications.
● Understand and follow all the safety instructions contained in

WARNING
Measurement Category
O Circuits which are not directly connected to the mains
power supply.
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.

Interior wiring
● Never make measurements under the circumstances exceeding
the designed measurement category and the rated voltage of
the instrument and the test leads.
● 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.
● Never attempt to use the instrument if its surface or your hand
is wet.
● Do not exceed the maximum allowable input of any measuring
range.
● Never open the Battery cover during a measurement.
● To avoid electrical shock by touching the equipment under test
or its surroundings, be sure to wear insulated protective gear.
● Never measure current while the test leads are inserted into the
input terminals.
● Test leads to be used for voltage. Measurements shall be rated
as appropriate for Measurement Category III or IV according to
IEC 61010-031 and shall have a voltage rating of 600V or
higher.
● Barriers on the instrument body and the test leads provide
protection to keep your fingers and hands from touching an
object under test. Keep your fingers and hands behind the
barriers during measurement.
DANGER
● Never attempt to make measurement if any abnormal
conditions, such as broken case and exposed metal parts are
found on the instrument or test leads.
● Verify proper operation on a known source before use
or take action as a result of the indication of the instrument.
● Firmly attach the caps to the test leads when performing
measurements in CAT III or higher test environments. When
K2007R and the test leads are combined and used together,
whichever is lower category & voltage to earth either of them
belong to is applied.
● Do not rotate the Function Switch if the instrument and the
equipment under test are connected.
● Do not install substitute parts or make any modification to the
instrument. For repair or re-calibration, return the instrument to
your local Major Tech distributor
WARNING
● Use of this instrument is limited to domestic, commercial and
light industry applications. Strong electromagnetic interference
or strong magnetic fields, generated by large currents, may
cause malfunction of the instrument.
● Connect the test leads to the terminals firmly.
● This instrument isn't water proofed. Keep away from water.
● Do not pull or twist the test leads to prevent the risk of
damage.
● Power off the instrument after use. Remove batteries if the
instrument is to be stored and will not be in use for a long
period.
● Do not expose the instrument to the direct sunlight, high
temperature and humidity or dewfall.
● Use a cloth dipped in water or neutral detergent for cleaning the
instrument. Do not use abrasives or solvents.
CAUTION
NOTE
● The LCD shows some digits at the AC V and the DC V
ranges even while the test leads are open. In addition,
the LCD shows some digits instead of 0 when short-
circuiting the test leads. However, these phenomena
don't affect measurement results.

1.5V batteries.
(4) Install the Battery Compartment Cover and tighten the screw.
● Replace the batteries when a Low Battery Voltage warning " "
mark is indicated on the LCD. Otherwise, precise measurement
cannot be made.
If batteries are completely exhausted, the LCD goes blank without
showing " " mark.
