Safety Information
This device is designed to comply with IEC 61010 Safety
Standards, and has been thoroughly tested for safety prior to
shipment. However, mishandling during use could result in
injury or death, as well as damage to the device. Be certain
that you understand the instructions and precautions in the
manual before use. We disclaim any responsibility for acci-
dents or injuries not resulting directly from device defects.
In the manual, the symbol indicates particularly important
information that the user should read before using the device.
The symbol printed on the device indicates that the user
should refer to a corresponding topic in the manual (marked
with the symbol) before using the relevant function.
Indicates that incorrect operation presents an extreme
hazard that could result in serious injury or death to the
user.
Indicates that incorrect operation presents a possibility
of injury to the user or damage to the device.
Indicates advisory items related to performance or cor-
rect operation of the device.
Operating Precautions
The sensor detector window reflects irradiated laser
light. Under certain circumstances even this reflected
light can reach levels dangerous to the eye, poten-
tially causing blurring or loss of vision, so please use
sufficient caution when handling.
• To prevent malfunctions in the 3664 or the optical sensor,
avoid connecting or disconnecting the optical sensor con-
nector while power for the 3664 is ON.
• To avoid damaging the optical sensor and to ensure accurate
measurements, avoid dropping or applying any physical
shock to the optical sensor.
• Avoid touching the detector window with your bare hands.
The detector window must be clean for the sensor to meet
the specified performance parameters.
• 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.
• To avoid breaking the cables, do not bend or pull them.
• To avoid broken wires, always grasp the plug to disconnect
the optical sensor connector. Avoid pulling on the cable itself.
• When measuring an extremely concentrated beam the opti-
cal power density on the sensor may become excessive and
accurate measurement may not be possible. This may also
cause the sensor to wear out. In order to avoid a loss of sen-
sor sensitivity, use the 9743-10 under conditions where the
optical power density is 10 mW /mm2or less when the inci-
dent power is 50 mW or less.
• When the incident power is greater than 50 mW position the
sensor so that the beam size is as large as possible on the
sensor detector window. Incident power of 100 mW is pos-
sible if the full area is irradiated.
• Make sure no stress is applied to the repeater cable between
the sensor main unit and its light-receiving element.
• This device is not designed to be entirely water- or dust-proof.
Do not use it in an especially dusty environment, nor where it
might be splashed with liquid. This may cause damage.
• This device is designed for use indoors. It can be operated
at temperatures between 0 and 40°C (32 and 104°F) without

Safety Information
This device is designed to comply with IEC 61010 Safety
Standards, and has been thoroughly tested for safety prior to
shipment. However, mishandling during use could result in
injury or death, as well as damage to the device. Be certain
that you understand the instructions and precautions in the
manual before use. We disclaim any responsibility for acci-
dents or injuries not resulting directly from device defects.
In the manual, the symbol indicates particularly important
information that the user should read before using the device.
The symbol printed on the device indicates that the user
should refer to a corresponding topic in the manual (marked
with the symbol) before using the relevant function.
Indicates that incorrect operation presents an extreme
hazard that could result in serious injury or death to the
user.
Indicates that incorrect operation presents a possibility
of injury to the user or damage to the device.
Indicates advisory items related to performance or cor-
rect operation of the device.
Operating Precautions
The sensor detector window reflects irradiated laser
light. Under certain circumstances even this reflected
light can reach levels dangerous to the eye, poten-
tially causing blurring or loss of vision, so please use
sufficient caution when handling.
• To prevent malfunctions in the 3664 or the optical sensor,
avoid connecting or disconnecting the optical sensor con-
nector while power for the 3664 is ON.
• To avoid damaging the optical sensor and to ensure accurate
measurements, avoid dropping or applying any physical
shock to the optical sensor.
• Avoid touching the detector window with your bare hands.
The detector window must be clean for the sensor to meet
the specified performance parameters.
• 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.
• To avoid breaking the cables, do not bend or pull them.
• To avoid broken wires, always grasp the plug to disconnect
the optical sensor connector. Avoid pulling on the cable itself.
• When measuring an extremely concentrated beam the opti-
cal power density on the sensor may become excessive and
accurate measurement may not be possible. This may also
cause the sensor to wear out. In order to avoid a loss of sen-
sor sensitivity, use the 9743-10 under conditions where the
optical power density is 10 mW /mm2or less when the inci-
dent power is 50 mW or less.
• When the incident power is greater than 50 mW position the
sensor so that the beam size is as large as possible on the
sensor detector window. Incident power of 100 mW is pos-
sible if the full area is irradiated.
• Make sure no stress is applied to the repeater cable between
the sensor main unit and its light-receiving element.
• This device is not designed to be entirely water- or dust-proof.
Do not use it in an especially dusty environment, nor where it
might be splashed with liquid. This may cause damage.
• This device is designed for use indoors. It can be operated
at temperatures between 0 and 40°C (32 and 104°F) without
degrading safety.

Operating Precautions
The sensor detector window reflects irradiated laser
light. Under certain circumstances even this reflected
light can reach levels dangerous to the eye, poten-
tially causing blurring or loss of vision, so please use
sufficient caution when handling.
• To prevent malfunctions in the 3664 or the optical sensor,
avoid connecting or disconnecting the optical sensor con-
nector while power for the 3664 is ON.
• To avoid damaging the optical sensor and to ensure accurate
measurements, avoid dropping or applying any physical
shock to the optical sensor.
• Avoid touching the detector window with your bare hands.
The detector window must be clean for the sensor to meet
the specified performance parameters.
• 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.
• To avoid breaking the cables, do not bend or pull them.
• To avoid broken wires, always grasp the plug to disconnect
the optical sensor connector. Avoid pulling on the cable itself.
• When measuring an extremely concentrated beam the opti-
cal power density on the sensor may become excessive and
accurate measurement may not be possible. This may also
cause the sensor to wear out. In order to avoid a loss of sen-
sor sensitivity, use the 9743-10 under conditions where the
optical power density is 10 mW /mm2or less when the inci-
dent power is 50 mW or less.
• When the incident power is greater than 50 mW position the
sensor so that the beam size is as large as possible on the
sensor detector window. Incident power of 100 mW is pos-
sible if the full area is irradiated.
• Make sure no stress is applied to the repeater cable between
the sensor main unit and its light-receiving element.
• This device is not designed to be entirely water- or dust-proof.
Do not use it in an especially dusty environment, nor where it
might be splashed with liquid. This may cause damage.
• This device is designed for use indoors. It can be operated
at temperatures between 0 and 40°C (32 and 104°F) without
degrading safety.
