Preface
Description
The KJM6335 is capable of measuring the amount of jitter in CD
players by the time interval method. Measurements of jitter in CD
players and other equipment can be achieved using this instrument
alone.
Because the KJM6335 incorporates a the symmetry follow-up
circuit, PLL clock-regeneration circuit, and phase-difference
correction circuit, it eliminates the need for externally provided
circuits.
The response characteristics of symmetry follow-up or PLL clock
regeneration in the CD standard speed adhere to the Compact Disc
Reference Measuring Methods Specification Guideline Ver. 1.0 -
May 1999.
The instrument has an inhibit input feature that allows jitter
measurement with the undesired signal part masked.
GPIB interface is available as an option.
This Operation Manual applies to products running
ROM version 1.0x.
For reference to any product, please contact Kikusui distributor/
agent, and provide your instrument ROM version and serial
number given on the rear panel.
For checking the ROM version, see 3.3, "Checking the ROM
Version".

1-2 Setup KJM6335
1.2 Precautions for Installation
Be sure to observe the following precautions when installing the
meter.
■Do not use the meter in a flammable atmosphere.
To prevent explosion or fire, do not use the meter near alcohol,
thinner, or other combustible materials, or in an atmosphere
containing such vapors.
■Avoid locations where the meter is exposed to high
temperatures or direct sunlight.
Do not locate the meter near a heater or in areas subject to drastic
temperature changes.
Operating temperature range :0 °C to 40 °C (32°F to 104°F)
Optimum (specification guaranteed)
temperature range : 15 oC to 35 oC (59°F to 95°F)
Storage temperature range :-20 °C to 60 °C (-4°F to 140°F)
■Avoid humid environments.
Do not locate the meter in a high-humidity environment—near a
boiler, humidifier, or water supply.
Operating humidity range: 20 % to 85 % R.H
(no dew condensation is allowed)
Storage humidity range: 90 % R.H or less
(no dew condensation is allowed)
Condensation may occur even within the operating humidity
range. In that case, do not start using the meter until the location is
completely dry.
■Do not place the meter in a corrosive atmosphere.
Do not install the meter in a corrosive atmosphere or one
containing sulfuric acid mist or the like. This may cause corrosion
of various conductors and imperfect contact with connectors,
leading to malfunction and failure, or in the worst case, a fire.
■Do not locate the meter in a dusty environment.
Dirt and dust in the meter may cause electrical shock or fire.

KJM6335 Setup 1-3
■Do not use the meter where ventilation is poor.
Provide sufficient space around the meter. Otherwise, heat may
accumulate in the meter, resulting in fire.
■Do not place any object on the meter.
Particularly a heavy one, as doing so could result in a malfunction.
■Do not place the meter on a tilted surface or in a
location subject to vibrations.
If placed on a non-level surface or in a location subject to vibration,
the meter may fall, resulting in damage and injury.
■Do not use the meter in locations affected by strong
magnetic or electric fields.
Operation in a location subject to magnetic or electric fields may
cause the meter to malfunction, resulting in electrical shock or fire.
■Secure adequate space around the power plug.
Do not insert the power plug to an outlet where accessibility to the
plug is poor. And, do not place objects near the outlet that would
result in poor accessibility to the plug.
1.3 Precautions on Moving
When moving or transporting the meter to an installation site,
observe the following precautions.
■Turn the POWER switch off.
Moving the meter with the power on may result in electrical shock
or damage.
■Remove all wirings connected.
Moving the meter with cables connected may break the cables or
cause the meter to fall, resulting in injury.
■For transportation, use the special packing material for
the meter.
Transport the meter in its original package to prevent vibration and
falls, which may damage the meter.

1-4 Setup KJM6335
1.4 Checking the Line Voltage and Fuse
This meter is used by selecting one of the four line voltage ranges
specified in Table1-1. Check the default settings to determine
whether the voltage is suitable for your meter. Use a input power
fuse appropriate for your line voltage range.
WARNIN
G
• To prevent electric shock, be sure to unplug the AC
power cord before checking or replacing the fuse.
CAUTION
• Make sure that the fuse used conforms to the meter
specifications, including shape, rating, and
characteristics. Using a fuse with different rating or
short-circuiting, the fuse holder will damage the
meter.
When checking or changing the line voltage range, or when
checking or replacing the power fuse, observe the following
instructions:
1. Turn off the POWER switch and disconnect the power cord.
2. Remove fuse holder as shown in Fig. 1-2 "Removing Fuse
Holder".
3. Referring to the LINE VOLTAGE table on the rear panel,
check the rating and blowing characteristic of the fuse
mounted. If a wrong fuse is used, replace it.
Table 1-1 LINE VOLTAGE
4. Check the line voltage to use from the LINE VOLTAGE
table, adjust the voltage selector to the ▼mark and push in
the cover.

Overvoltage Category III or IV.
• The power cord for 100-V system has a rated
voltage of 125 VAC. If this power cord is used at the
line voltage of a 200-V system, replace the power
cord with that satisfying that line voltage.
Have a qualified engineer select the appropriate
power cord. If obtaining the right power cord is
difficult, contact Kikusui distributor/agent.
• Do not use the power cord that comes with the product
as a power cord for other equipment.

1.6 Grounding
WARNIN
G
• Not grounding the meter creates danger of electric
shock.
• Connect the ground terminal to an electrical ground
(safety ground).
CAUTION
• Not performing adequate grounding work on the
meter results in malfunction or the production of
large noises from the meter.
To ensure safety, provide secure grounding.
The meter can be grounded by one of the two methods specified
below. Select one, and ground the meter securely.
a. Plug the AC power cord into a
3-pole power outlet upon
which grounding construction
has been performed.
b. Connect terminal on the
meter rear panel to the ground
terminal (GND).
