IV Overvoltage category KJM6310
Over v olta g e categor y
F or the safe use of equipment, IEC60664 (Insulation coordi-
nation for equipment within low-voltage systems) classifies
circuits into four categories by an occurrence level of tran-
sient voltage. When you connect equipment to a power line
or connect a measuring instrument to these places, make
sure of the applied overvoltage category. This instrument is
designed to operate from the overvoltage category II.
Overvoltage category I
• Equipment of o v erv oltage cate gory I is equipment for connec -
tion to circuits in which measures are tak en to limit transient
o v erv oltages to an appropriately lo w le v el.
Examples are protected electronic circuits.
Ov er v oltage categor y II
• Equipment of o v erv oltage cate gory II is ener gy-consuming
equipment to be supplied from the fi x ed installation.
Examples of such equipment are appliances, portable tools and
other household and similar loads.
If such equipment is subjected to special requirements with
re g ard to reliability and a v ailability , o v erv oltage cate gory III
applies.
Ov er v oltage categor y III
• Equipment of o v erv oltage cate gory III is equipment in fi x ed
installations and for cases where the reliability and the a v ail -
ability of the equipment is subject to special requirements.
Examples of such equipment are switches in the fi x ed installa -
tion and equipment for industrial use with permanent connec -
tion to the fi x ed installation.
Ov er v oltage categor y IV
• Equipment of o v erv oltage IV is for use at the origin of the
installation.
Example of such equipment are electricity meters and primary
o vercurrent protection equipment.

About This Manual
This operation manual describes the KJM6310 Time Interval Jitter
Meter.
■ROM version of the product to which this manual
applies
• Ver. 1.0 X
The *IDN? message is used to verify the version. For a description of
the *IDN? message, see chapter 4, “RS-232C Control."
When contacting us about the product, please provide us the version
number and the manufacturing number that are attached to the rear
panel.
Product Overview
The KJM6310 is an instrument used to measure jitters of CDs. It can
measure the RF to CLOCK jitter by the time interval method.
The KJM6310 can be used for the development, adjustment, and
inspection of optical pickups.
It is a compact unit for embedded applications that is designed to
maximize the work efficiency on the production line.
To provide the KJM6310 at low cost, the item to be measured has
been limited to CDs, and meters and panel switches have been
removed. The KJM6310 is designed to be used on a single adjustment
line. However, peripheral circuits required for making measurements
such as symmetry follow-up circuit, PLL clock regeneration circuit,
and phase-difference correction circuit are equipped as standard.

1.2 Installation
How to install the KJM6310
■ The KJM6310 is designed for embedded application
and provides attachment screw holes on the side
and bottom panels. To fix the KJM6310 in place, use
these screw holes. If you are not fixing the KJM6310
in place, attach the stand provided to the bottom
panel and place the KJM6310 so that it stands up.
Secure adequate space around the KJM6310 so
that air can circulate around it.
Precautions concerning installation location
This section describes the precautions to be taken when installing the
KJM6310. Make sure to observe them.
■ Do not use the KJM6310 in a flammable atmosphere.
To prevent the possibility of explosion or fire, do not use the
KJM6310 near alcohol, thinner or other combustible materials, or in
an atmosphere containing such vapors.
■Avoid locations where the KJM6310 is exposed to
high temperature or direct sunlight.
Do not place the KJM6310 near a heater or in areas subject to drastic
temperature changes.
Operating temperature range: 0 °C to 40 °C

KJM6310 Setup 1-3
■Avoid humid environments.
Do not place the KJM6310 in high-humidity locations--near a boiler,
humidifier, or water supply.
Operating humidity range: 20 % to 85 % RH (no condensation)
Storage humidity range: 0 to 90 % RH (no condensation)
Condensation may occur even within the operating humidity range.
In such cases, do not use the KJM6310 until the condensation dries
up completely.
■ Do not place the KJM6310 in a corrosive atmosphere.
Do not install the KJM6310 in a corrosive atmosphere or in environ-
ments containing sulfuric acid mist, etc. This may cause corrosion of
various conductors and bad contacts of connectors inside the
KJM6310 leading to malfunction and failure, or in the worst case, a
fire.
■Do not place the KJM6310 in a dusty location.
Accumulation of dust can lead to electric shock or fire.
■Do not place the KJM6310 on an inclined surface
or location subject to vibrations.
The KJM6310 may fall or tip over causing damages and injuries.
■Do not use the KJM6310 in a location subject to
strong magnetic or electric fields.
The KJM6310 may malfunction and cause electric shock or fire.
■Do not place objects on top of the KJM6310.
Placing objects on top of the KJM6310 can cause failures (especially
heavy objects).

1-4 Setup KJM6310
1.3 Precautions When Moving the KJM6310
When moving the KJM6310 to the installation location or when
transporting the unit, note the following points.
■Always turn off the POWER switch.
Moving the KJM6310 with the power on may result in electric shock
or damage.
■When moving the KJM6310, remove all wires that
are connected.
Moving the KJM6310 with the cables connected can cause wires to
break or injuries due to the KJM6310 falling over.
■When transporting the KJM6310, be sure to use
the original packing materials.
If packing materials are not used, damage may result from vibrations
or from the KJM6310 falling during transportation. If you need pack-
ing materials, contact your Kikusui agent or distributor.
1.4 Connecting the DC Power Supply
Using the DC plug provided, connect a 15-V DC power supply to the
DC INPUT connector on the rear panel.
Input line voltage range 14.5 VDC to 15.5 VDC
•Be sure the polarity of the connector is correct. If the
polarity is reversed, the internal fuse will blow.
• Do not connect a power supply outside the input line
voltage range as it may cause a malfunction.
•The KJM6310 is designed to be connected to a power
supply classified as Overvoltage Category I (SELV-E).
Do not connect to a power supply classified as Over-
voltage Category II, III, or IV. For a description of the
Overvoltage Category, see “Overvoltage Category” on
page IV.
