Measurement categories (Overvoltage categories)
To ensure safe operation of measurement instruments, 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 instrument in an environment
designated with a higher-numbered category than
that for which the instrument is rated could result in a
severe accident, and must be carefully avoided.
Never use a CAT I measuring instrument in CAT II,
III, or IV environments.
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).
6
The measurement categories comply with the Overvoltage Categories of the IEC60664 Standards.
7
Follow these precautions to ensure safe operation
and to obtain the full benefits of the various functions.
Usage Notes
• When cleaning the connector of a optical
fiber cable, never look directly into the end
of the optical fiber cable or observe it
through a magnifying glass if the cable is
connected to an operating optical output
device as this can lead to eye damage or
visual impediment.
• To avoid a shock hazard, disconnect the
USB cable before replacing the batteries.
8
• Do not store or use the product where it could
be exposed to direct sunlight, high temperature
or humidity, or condensation. Under such conditions, the product may be damaged and insulation may deteriorate so that it no longer meets
specifications.
• To avoid damage to the product, do not allow
the product to get wet, and do not use it when
your hands are wet.
• Do not use the product where it may be exposed
to corrosive or combustible gases. The product
may be damaged.
• To avoid damage to the product, protect it from
vibration or shock during transport and handling,
and be especially careful to avoid dropping.
• The mating portions of the detector and of the
connector adapter are high-precision machined
parts. Make sure that these portions are free of
dust or other foreign matter when connecting
them. In particular, the detector window requires
meticulous care. If there is dust in the interface
or a scratch on the detector window, the meter
may not satisfy performance specifications.

Dust
• After use, always turn OFF the power.
• Be sure to replace the cap to protect the device
from dust when the meter is not in use.
• The “ ” indicator appears when battery voltage
becomes low. Replace the batteries as soon as
possible.
• Use the specified battery (LR6 alkaline battery)
only. Other batteries (manganese batteries, for
example) run out more quickly than alkaline batteries.
9
Handling Optical Fiber Cable
Follow the precautions below to prevent damage
to the optical fiber cables.
• Do not insert at an angle.
• Do not bend the cable at the neck of the connector.
• Do not bend or twist.
• Do not pull forcefully.
• Do not allow cable to kink.
• Do not touch the end face (ferrule).
10
Care and handling of CD-R
• Always hold the disc by the edges, so as not to
make fingerprints on the label side or scratch
the printing.
• Never touch the recorded side of the disc. Do
not place the disc directly on anything hard.
• Do not wet the disc with volatile alcohol or water,
as there is a possibility of the label printing disappearing.
• To write on the disc label surface, use a spiritbased felt pen. Do not use a ball-point pen or
hard-tipped pen, because there is a danger of
scratching the surface and corrupting the data.
Do not use adhesive labels.
• Do not expose the disc directly to the sun's rays,
or keep it in conditions of high temperature or
humidity, as there is a danger of warping, with
consequent loss of data.
• To remove dirt, dust, or fingerprints from the
disc, wipe with a dry cloth, or use a CD cleaner.
Always wipe radially from the inside to the outside, and do no wipe with circular movements.
Never use abrasives or solvent cleaners.
• Hioki shall not be held liable for any problems
with a computer system that arises from the use
of this CD-R, or for any problem related to the
purchase of a Hioki product.

1.1 Product Overview
The 3661-20 OPTICAL POWER METER is an
optical power measuring instrument for optical
fiber cables. The meter has two measurement
modes: optical-power measurement mode and
optical-loss measurement mode. In optical-loss
measurement mode, the meter calculates optical
loss by using the measurement and the reference
value stored in the memory.
Memory functions and a USB interface are provided so that saved measurement values can be
transferred to a PC using the supplied software.

Two Measurement Modes
(Optical power measurement mode)
Measures the optical power of the cable connected to the meter.
(Optical loss measurement mode)
Stores a reference measurement in advance, then
takes a measurement and calculates optical loss
from the measurement and the reference.
Measurement wavelengths are programmable in 5 nm steps
Using the supplied software, practically any wavelength can be programmed for measurement in 5
nm steps. Up to eight programmed wavelengths
are stored in internal memory, and optical power
can be measured at each stored wavelength.
Supports Two Types of Optical Connectors
Supports both FC and SC type optical connectors;
use an appropriate connector adapter (a second
adapter is optional).
Memory Function
Saves measurements in the built-in memory; up to
1000 measurements per programmed measurement wavelength can be stored.
Transferring Data to PC
The provided USB interface enables saved data to
be transferred to a PC using the supplied software.
Auto Power Save Function
If there is no key operation for more than approximately ten minutes, the power of the meter is automatically turned off. This prevents the meter from
being left on unintentionally and minimizes battery
consumption.

2.1 Connecting Connectors
When cleaning the connector of a optical
fiber cable, never look directly into the end of
the optical fiber cable or observe it through a
magnifying glass if the cable is connected to
an operating optical output device as this can
lead to eye damage or visual impediment.
Make sure that the mating portions are free of dust
or other foreign matter when connecting a optical
fiber cable to the meter. In particular, the end face
(ferrule) requires meticulous care. If there is dust
in the interface or a scratch on the end face, the
measurement may not be accurate.
Always clean the optical connector end face
(ferrule) of the optical fiber cable before connecting.
