DESIGNATIONS
SAFETY WARNINGS
This instrument has been designed and tested according to IEC
Publication 61010; Safety Requirements for Electronic Measuring
Apparatus. This Instruction manual contains warnings and
safetyrules 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 instruction before using
the instrument.
The voltage values used in this manual or on the meter are given
in line voltage, unless otherwise specified.
#
DANGER
● Never make measurement on a circuit in which earth potential
of 600V or higher exist.
● Do not attempt to make measurement in the presence of
flammable gasses, fumes, vapor or dust. 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.
● T h e i n s t r u m e n t s h o u l d b e u s e d o n l y i n i t s i n t e n d e d
applications or conditions. Otherwise, safety functions
equipped with the instrument do not work, and instrument
damage or serious personal injury may be caused.
● Verify proper operation on a known source before use or
taking action as a result indication of the instrument.
● Keep your fingers and hands behind the protective fingerguard
during measurement.
#
WARNINGS
● N ever attempt to make any measurement, if the instrument
has any structural abnormality such as cracked case and
exposed metal part.
● S top using the test lead if the outer jacket is damaged and the
inner metal or color jacket is exposed.
● D o not install substitute parts or make any modification to
the instrument. Return the instrument to Kyoritsu or your
distributor for repair or re-calibration.
● D o not measure for more than five minutes when measuring
on 500V AC or more, although the instrument is designed for
the use 110V through 600V AC.The maximum time indicated
above is measured from the time when more than 2 test leads
of the unit are connected to the power supply cords.
● E xceeding the limited continuous testing duration or leaving
the instrument connected to the circuit under test may heat the
internal circuit and cause burn injuries or fire.
● If the all open phase lamps are not lit on, any phase may still
be live-be carefull.
#
WARNING
● Read through and understand instructions contained in this
manual before starting using the instrument.
● S ave and keep the manual handy 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
the manual.
Failure to follow the instructions may cause injury, instrument
damage and/or damage to equipment under test. Kyoritsu is by
no means liable for any damage resulting from the instrument
in contradiction to this cautionary note.

CAUTIONS
1. Make sure to never apply a voltage more than 600V ACrms.
between the test leads of the instrument and earth to avoid
damage to the instrument.
2. Do not measure for more than five minutes when measuring
on 500V AC or more, although the instrument is designed for
the use 110V through 500V AC.
Measurement categories (Over-voltage categories)
To ensure safe operation of measuring instruments, IEC61010
establishes safety standards for various electrical environments,
categorized as O to CAT Ⅳ, and called measurement
categories. Higher-numbered categories correspond to
electrical environments with greater energy, So a measuring
instrument designed for CAT Ⅲ environments gives greater
protection than one designed for CAT Ⅱ.
O (None, Other): Circuits which are not directly connected to
the mains power supply.
CAT Ⅱ: Fault category level at a mains socket
CAT Ⅲ: Fault category at distribution board level
CAT Ⅳ: The circuit from the service drop to the power meter and
primary over-current protection device (distribution panel).
O: Device which is
not directly
connected to the
mains power supply
