11. 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 When Using the Instrument
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) Never disassemble the instrument.
7) An SC connector and FC connector are available for the instrument.
Always use an optical connector that matches the instrument.
Forcibly attaching a connector can damage the optical input section.
8) Looking at the optical fiber, end of the optical connector, or other
items that connect to the light source can result in damage to the eyes
from lasers.
9) Do not use an optical connector with an angled ferrule. Doing so can
damage the optical input section.
10) Incidence of excessive light outside of the optical power measuring
range can damage the sensor element. Be aware that especially
with low duty, high-peak pulses, when the optical power is expressed
as an average the value appears low, but the instantaneous power
can be quite high.
11) If the optical connector attached to the optical input connector is
damaged, dirty, or otherwise compromised, the instrument will be
unable to perform as expected. At worst, this may cause damage to
the instrument’s optical connector.
12) When attaching the optical connector, take care not to damage the
optical input end.
13) When not using the instrument, attach the optical input connector cap
to protect the connector from dirt, grime, and other foreign particles.
14) If the optical input end or connector is soiled with dirt or grime, clean
the end with commercially available optical connector cleaner.
