1. Safety warnings
○ This instrument has been designed, manufactured and tested
according to IEC 61010-1: Safety requirements for Electronic
Measuring apparatus, and delivered in the best condition
after passing quality control tests. This instruction manual
instrument and to maintain it in safe condition.
  Therefore, read through these operating instructions before
using the instrument.
#
DANGER
● Read through and understand instructions contained in this
manual before using the instrument.
● Keep the man ual at ha nd to ena ble qui ck ref erenc e
whenever necessary.
● Th e instr ume nt is to be us ed onl y in its i ntend ed
applications. The operating instructions described in the
manual must be observed.
● Understand and follow all the safety instructions contained
in the manual.
It is e ssential that th e above instructions are adhered to.
Failure to follow the above instructions may cause injury,
instrument damage and/or damage to equipment under test.
KYORITSU is not liable for any damage resulting from the
users mishandling of the instrument.
The symbol
#
indicated on the instrument, means that the
user must refer to the related parts in the manual for safe
op erati on of th e inst rume nt. It is e sse ntial to r ead th e
instructions wherever the

DANGER is reserved for conditions and actions that are
likely to cause serious or fatal injury.
#
WARNING is reserved for conditions and actions that can
cause serious or fatal Injury.
#
CAUTION is reserved for conditions and actions that can
cause minor injury or instrument damage.
#
DANGER
● Never make measurement on a circuit in which the electrical
potential exceeds AC300V.
● Verify proper operation on a known source before use or
taking action as a result of the indication of the instrument.
● Do not make measurement when thunder rumbling. If the
instrument is in use, stop the measurement immediately and
remove the instrument from the equipment under test.
● Do not attempt to make measurement in the presence of
flammable gasses. Other wise, the use of the instrument
may cause sparking, which can lead to an explosion.
● Use insulated protective gears, such as insulated gloves, for
your s afety when possible e lec tric s hoc k haz ards ar e
concerned.
● The transformer jaws are made of metal and their tips are
not completely insulated. Be especially careful about the
possible shorting where the measured object has exposed
metal parts.
● Never use this instrument when its surface or your hand is
wet. Do not wet the output terminal because it is not dust/
waterproof.
● Do not exceed the maximum allowable input of any
measuring range.
#
WARNING
● Never attempt to make any measurement, if any abnormal
conditions are noted, such as broken case, and exposed
metal parts.
● Do not install substitute parts or make any modification to
the i nstr umen t. Retur n the in str ument to yo ur loc al
KYORITSU distributor for repair or re-calibration in case of
suspected faulty operation.
● Always keep your fingers and hands behind the barrier on
the instrument to avoid the possible shock hazard.
#
CAUTION
● Do not step on or pinch the cord to prevent the jacket of
cord from being damaged.
● The output terminal shall be removed or connected without
clamping a conductor. Otherwise, it may cause a failure.
● Do n ot expose the instr ument to direct sunlight , high
temperatures, humidity or dew.
● Never give shocks, such as vibration or drop, which may
damage the instrument.
● Use a damp cloth with wat er and ne utra l deter gent for
cleaning the instrument. Do not use abrasives or solvents.
● This instrument is not designed to be dust or waterproof. Do
not use it dusty places or where the instrument is likely to be
wet.
 It may cause troubles on the instrument.
● Never pinch foreign matters or give vibrations at the jointed
parts of this instrument. Otherwise, matching area of Jaws
may be d ama g e d and c a use i n f lu enc es o n th e
measurements.
● Do not bend or pull the root of the cable in order to prevent
breaks in the cable.
● Accurate measurement may not be obtained in the vicinity
of strong magnetic fields such as transformers, high-current
circuits or wireless machines.

4. Operating instructions
#
DANGER
● Never make measurement on a circuit in which the electrical
potential exceeds AC300V in order to avoid possible shock
hazard.
● The transformer jaws are made of metal and their tips are
not completely insulated. Be especially careful about the
possible shorting where the measured object has exposed
metal parts.
#
CAUTION
● Take sufficient care to avoid shock, vibration or excessive
force when handling the instrument. Otherwise, precisely
adjusted transformer jaws will be damaged.
● When transformer jaws do not fully close, never try to close
them by force, but make them free to move and try again. If
a foreign substance is stuck in the jaw tips, remove it.
● Do not force to open the Transformer jaws when they are
frozen.
● When making current measurements, keep the transformer
jaws fully closed. Other wise, ac curate measurements
ca nnot be taken. Maxim um co nduct or size i s approx
φ24mm.
● Hold the inserting part (except for the cable) and disconnect
the Output terminal from the measuring instrument so as not
to cause a break in the cord.
Measurement procedures
(1) Connect the Output terminal t o the Inp ut terminal o f the
measuring instrument.
(2) Press the Trigger to open the transformer jaws and clamp
center of the closed transformer jaws.
(3)Ensure that the tips of transformer jaws are firmly closed.
