Installation Conditions
To ensure safe operation, the following recommendations should be
observed:
(1) Do not operate the instrument under voltage fluctuations exceeding
10% of the recommended line voltage. Large fluctuations may
cause the instrument to fail.
(2) Use a three-pronged electrical outlet with a ground. When only a
two-pronged socket is available, use an adapter and be sure to
connect the ground wire of the adapter.
(3) Operate the instrument under a temperature range of 10 ∼ 30°C.
(4) Operate the instrument under a humidity range of 35 ∼ 85% (RH).
If ambient humidity exceeds 85% (RH), water vapor may deteriorate
optical components. If possible, install the instrument in a location
having a humidity of 60% or lower.
(5) Operate the instrument under an atmospheric pressure of 750 ∼
1060 hPa.
(6) Avoid strong magnetic fields and sources of high-frequency waves.
The instrument may not function properly when near strong
magnetic fields or high-frequency wave sources.
(7) Avoid vibrations caused by vacuum pumps, electric motors,
processing equipment and machine tools.
(8) Avoid dust and corrosive gas. Do not install the instrument in a
location where it may be exposed to dust, especially in locations
exposed to outside air or ventilation outlets that discharge dust
particles.
(9) Do not install the instrument in a location where it may be exposed
to direct sunlight.
(10) Do not install the instrument in a location where it may be directly
exposed to the air current from an air conditioner or heater, as such
a location may inhibit stable measurement.
Note: The above conditions do not ensure optimal performance of this
instrument.
