The smallest displayable unit on a digital
measuring product, i.e., the input value that causes
the digital display to show a "1".
The following symbols in this manual indicate
the relative importance of cautions and
warnings.
Accuracy
We define measurement tolerances in terms of
rdg. (reading) values, with the following
meanings:

_____________________________________________
CAT I Secondary electrical circuits connected to an AC electrical
outlet through a transformer or similar device.
CAT II Primary electrical circuits in equipment connected to an AC
electrical outlet by a power cord (portable tools, household
appliances, etc.)
CAT III Primary electrical circuits of heavy equipment (fixed
installations) connected directly to the distribution panel, and
feeders from the distribution panel to outlets.
CAT IV The circuit from the service drop to the service entrance,
and to the power meter and primary overcurrent protection
device (distribution panel).
Measurement categories (Overvoltage categories)
This product complies with CAT I safety requirements.
To ensure safe operation of measurement products, IEC
61010 establishes safety standards for various electrical
environments, categorized as CAT I to CAT IV, and
called measurement categories. These are defined as
follows.
Higher-numbered categories correspond to electrical
environments with greater momentary energy. So a
measurement device designed for CAT III environments
can endure greater momentary energy than a device
designed for CAT II. Using a measurement product in an
environment designated with a higher-numbered category
than that for which the product is rated could result in a
severe accident, and must be carefully avoided.
Never use a CAT I measuring product in CAT II, III, or IV
environments. The measurement categories comply with
the Overvoltage Categories of the IEC60664 Standards.

DANGER
To prevent electric shock, do not connect the
test terminals to a UTP cable, etc., that is
connected to an operational network. The test
terminals (RJ-45) for this device are specifically
designed for checking standalone UTP cables.
WARNING
To avoid electric shock, do not allow the
product to get wet, and do not use it when your
hands are wet.
Do not connect this device to a UTP cable while
the device is wet. Doing so could result in
electric shock.
Do not use the product where it may be
exposed to corrosive or combustible gases. The
product may be damaged or cause an

To avoid a shock hazard, disconnect the UTP
cable before replacing the batteries. Before
using the product after replacing the batteries,
replace the cover and screw.
Do not mix old and new batteries, or different
types of batteries. Also, be careful to observe
battery polarity during installation. Otherwise,
poor performance or damage from battery
leakage could result.
Notes on Use
Follow these precautions to ensure safe
operation and to obtain the full benefits of the
various functions.

and be especially careful to avoid dropping.
Adjustments and repairs should be made only by
technically qualified personnel.
NOTE The indicator appears when battery voltage
becomes low. Replace the batteries.
Always turn the power switch off after you are
done using the unit.
Do not use any power source other than the
specified batteries (LR6/AA). Using

Overview
1.1 Product Overview
The 3660 can check the connection status
between RJ-45 connectors attached to the near
and far ends of a UTP cable (wiremap), and
can check the length of a cable. Furthermore,
when used with the optional 9337 DIRECTION
TERMINATOR, the 3660 can be used to identify
specific cables among many when cables are
laid inside a wall or under the floor. Once the
RJ-45 connectors have been attached, these
functions can be easily used to check
connections and identify cables during
installation work. The 3660 is also
demonstrates its power when it is needed to
check cables in the event of a network failure
caused by an open circuit or a short circuit in a
cable.

1.2 Features
(1) Simple operation
Once the 3660 and the 9336 WIREMAP
TERMINATOR have been connected to both
end of the UTP cable to be tested, the wiremap
check and cable length measurements can be
performed simply by pressing the TEST key.
(2) Easy to see display on large LCD
When using the wiremap check and cable
length measurement functions, the results of
the wiremap check and the cable length
measurement are displayed on the large LCD.
When using the direction check function, the
cable identification results are displayed on the
large LCD.
(3) Lengths displayed in meters (m) or feet (ft)
The 3660 can display cable lengths in meters
(m) or feet (ft).

2.1 Preparation for Checks
1. Turn the power switch on, and confirm
that the display (the LCD) is on.
2. Confirm that the battery mark ) is not
displayed. If it is displayed, the
battery is running low and needs to be
replaced. (Refer to section 7.1,
"Changing the battery.")

2.2 Checking Method
Checking after connecting the UTP cable connectors
The 3660's wiremap check function can be
used to check the connection status of the
connector pins.
(Refer to section 2.2.1.)
Use in analysis of problems in a working network
If there is an open circuit or a short circuit in a
UTP cable, the 3660's cable length
measurement function displays the distance
from the near end of a cable to an open circuit
or a short circuit in the cable. When a problem
occurs in a working network, the cable length
measurement function and the wiremap check
function can be used together to determine
whether the problem is caused by an open
circuit/short circuit in a cable, or some other
factor.
(Refer to section 2.2.1.)
Identification if individual cables installed in a group
When multiple cables are installed together, it
can be difficult to know which cable is
connected to what. When the 3660's direction
check function is used in conjunction with the
optional 9337 DIRECTION TERMINATOR, it
becomes easy to identify individual cables.
When used with the 9337, up to five cables can
be identified.
(Refer to section 2.2.2.)
