2.1 Handling Precautions
The following describes precautions that must be taken during use of the instrument.
This instrument utilizes ultra-precision optical components. In order for performance to
be guaranteed, please take note of the following.
Precautions during Use
1) Do not drop or expose the instrument to excessive physical shock. The
instrument is protected with plastic casing, but contains fragile optical
components.
2) Do not place the instrument in direct sunlight, or in high-temperature or highly
humid locations such as inside of a car for long periods of time.
3) Do not bring the instrument close to strong electromagnetic waves. Doing so
can lead to malfunction.
4) Do not use the instrument and mobile phones simultaneously in the same
vicinity.
5) The instrument is portable and can be used outdoors under battery power, but
is not waterproof. Never operate the instrument in the rain.
6) Do not disassemble the device.
7) Do not peer into the ends of the optical fiber, the beams as they travel through
the air, the optical connector, or other parts connected to the light source.
Doing so can result in injury to the eyes from lasers. Take appropriate caution
when handling.
8) Incidence of excessive or highly concentrated light outside of the optical power
measuring range can damage the sensor element.
9) When the optical power is expressed as an average the value appears low,
but the instantaneous power can be quite high. Take extra precaution with low
duty, high-cusp pulses.
10) If the surface of the sensor is soiled with dirt or grime, clean the end with
specialized optical connector cleaner or a dust-resistant cloth.
11) If any plastic parts become soiled, wipe with a soft and dry cloth.
12) When not using the instrument, attach the cap to protect the sensor from dirt,
grime, and other foreign particles.
13) To prevent damage when attaching or removing the optical input connector
cap, take care not to rub the connector against the cap.
14) Never insert or remove the sensor head while the power is ON.
15) Do not connect anything to the connectors (sensor head, analog out terminal,
etc.) other than the specified product. Damage can result.
16) The sensor head contains optical components that are easily scratched.
Take care not to scratch or crack any part of the sensor head.
17) Only turn ON the power if the sensor head is attached.
