1. SAFETY WARNINGS
Th is in st ru me nt has been de si gn ed an d tes te d acc or di ng
to IEC61010: Safet y requi remen ts for Elec tro nic Measu ring
App aratus, and de livered in the best condi tion after pas sing
quality control tests. This instruction manual contains warnings
and safet y rules whi ch have to be obs erved by the us er to
ensure safe operation of the instrument and to maintain it in safe
condition. Therefore, read through these operating instructions
before using the instrument.
WARNING
● Read through and understand instructions contained in this
manual before using the instrument.
● Ke ep the man ua l at ha nd t o ena b le qu i ck re f er en ce
whenever necessary.
● The instrument is to be used only in its intended applications.

DANGER
● Never make measurement on a circuit in which the electrical
potential exceeds AC600V.
● Do not make measurements when a thunder is rumbling.
St op measu re me nts imme di at ely an d dis co nn ect th e
instrument from the devices under test.
● Do not attempt to make measurements in the presence of
flammable gasses.
Otherwise, the use of the instrument may cause sparking,
which can lead to an explosion.
● Be especially careful about the possible shorting where the
measured conductor is not insulated.
● Never attempt to use the instrument if its surface or your
hand is wet.
● Remove the Measuring terminals from the circuit under test
before connecting / inserting the Output connector.
● Do n ot exc ee d th e ma xi mum all ow abl e in pu t of an y
measuring range.
● Confirm a proper operation of this sensor on a well-known
power source before taking countermeasures against the
measured results.
WARNING
● Never attempt to make any measurement if any abnormal
conditions, such as a broken cover or exposed metal parts
are present on the instrument.
● Do not install substitute parts or make any modification to the
instrument. Return the instrument to your local KYORITSU
distributor for repair or re-calibration in case of suspected
faulty operation.
● Keep your fingers and hands behind the safety barrier during
measurements.
CAUTION
● Do not step on or pinch the cord, or it may damage the jacket
of cord.
● Grasp the connector to remove the output terminal from the
instrument.
● Put the instrumen t on a st abl e place where is f ree from
vibrations or shocks.
● Firmly fix the Sensor unit and Measuring terminal so that
they don't fall off due to the weight of sensor or test leads.
●
Keep away Floppy Disks, Magnetic Cards, PCs and Displays
from the magnet, which is attached to the backside of the sensor.
● Do no t expose th e ins tr um en t to direct su nl ig ht , hig h
temperatures, humidity or dew.
● Not to give shocks, such as vibration or drop, which may
damage the instrument.
● Use a damp cloth with neutral deterg ent for cleaning the
instrument. Do not use abrasives or solvents.

◊ Measurement categories(Over-voltage categories)
To ensure safe operation of measuring instruments, IEC 61010
establishes safety standards for various electrical environments,
ca tegor iz ed as CAT.I to CAT.IV, and ca lled measurem en t
categories. Higher-numbered categories correspond to electrical
environments with greater momentary energy, so a measuring
instr um ent desig ne d fo r CAT.I II enviro nm ents can endu re
greater momentary energy than one designed for CAT.II.
CAT.I : Se co nd ar y electrical ci rc ui ts connected to an A C
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 : Th e ci rc uit fr om the s er vic e drop to t he ser vi ce
ent r an c e, an d to t he po wer m et er an d p ri m ary
overcurrent protection device (distribution panel).
