Overvoltage Categories (CAT)
To ensure safe operation of measurement instruments, IEC 60664
establishes safety standards for various electrical environments,
categorized as CAT I to CAT IV, and called overvoltage categories.
These are defined as follows.
1
CAT I
Secondary electrical circuits connected to an AC
electrical outlet through a transformer or similar
device.
2
CAT II
Primary electrical circuits in equipment connected to
an AC electrical outlet by a power cord (portable
tools, household appliances, etc.)
3
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).
4
5
6
7
8
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.

• An arbitrarily set measurement wavelength is automatically
saved in the measurement-wavelength memory.
• The measurement-wavelength memory holds up to 10 wavelengths (including preset wavelengths for each optical sensor).
• Each optical sensor has preset wavelengths. These preset
wavelengths cannot be edited.
• Through the setting operation for the arbitrary measurement
wavelength, the setting data is automatically saved in the measurement-wavelength memory. When it is necessary to save a
new measurement wavelength to the measurement-wavelength memory when the memory already contains 10 wavelengths, the oldest data is deleted in order to make space for
the new data.
• To reset the data in the measurement-wavelength memory,
perform measurement-wavelength-memory reset. This will
return the memory to its default state for each sensor.

3.4 Starting Measurement
• To ensure accurate measurements, make sure the detector
window is free of dust, stains, and any damage.
• Confirm that the light to be measured fits completely within the
detector window.
• If the optical power is too intense for the unit area, such as
when a condensed beam on the focus plane is measured, the
optical sensor may be saturated and the 3664 may not be able
to conduct accurate measurement. This problem can be
solved by changing the distance between the light source and
the detector window of the optical sensor.
• The operation of the light source may become unstable due to
the reflection of light from the detector window of the optical
sensor. This problem can be solved by angling the detector
window slightly to prevent the reflection from returning to the
light source.
• If background light, sunlight, illumination light, or any other light
than the light to be measured is overly intense, the 3664 may
not be able to conduct accurate measurement. Take appropriate light-shielding measures.

7.1.2 Cleaning of the Optical Sensors
• Avoid touching the detector window with your bare hands. The
detector window must be clean for the sensor to meet the specified performance parameters.
• With the exception of ethyl alcohol, avoid using organic solvents
to clean the detector window. These solvents can damage the
detector window.
• Avoid scratching the detector window with sharp or pointed
objects (e.g., the tips of tweezers) or against hard surfaces.
Damage to the detector window may prevent the sensor from
meeting specified performance parameters.
Take the cleaning method of the 9742 OPTICAL SENSOR as an
example.
1. Open the sensor cover.
(When using the 9742-10 OPTICAL SENSOR, take care to
avoid misplacing the sensor cover.
2. Wipe the detector window of the sensor using lens cleaning
paper or other lint-free material.
If lint remains on the detector window, blow off with an optical lens airbrush.
If the detector window is soiled, fluff the tip of a cotton swab.
Moisten the cotton tip in ethyl alcohol and wipe the surface.
7.2 Service
• If the instrument seems to be malfunctioning, confirm that the
batteries are not discharged, and that the USB cable is not open
circuited before contacting your dealer or Hioki representative.
• When sending the instrument for repair, remove the batteries and
pack carefully to prevent damage in transit. Include cushioning
material so the instrument cannot move within the package. Be
sure to include details of the problem. Hioki cannot be responsible for damage that occurs during shipment.

7.5 Replacing the Batteries
• To avoid electric shock, turn off the power switch and disconnect the USB cable before replacing the batteries.
• After replacing the batteries, replace the cover and screws
before using the instrument.
• 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.
• To avoid the possibility of explosion, do not short circuit,
disassemble or incinerate batteries.
• Handle and dispose of batteries in accordance with local
regulations.
• The “ ” indicator appears when battery voltage becomes low.
Replace the batteries as soon as possible.
• Use the specified battery (AA alkaline battery) only. If nonspecified battery such as a manganese battery is used, the
service hours may be shorter than when alkaline batteries are
used.
