Storage temperature: -20℃ ~ 60℃.
Atmosphere, gas:
Free from acid gas or alkaline gas and other gases that may corrode metals
significantly.
Free from gases that may dissolve paint such as from organic solvents
(particularly benzene, thinner or the like).
Other general notes:
Avoid direct sunlight (otherwise optical performance might deteriorate
or housing might be discolored). Avoid a window as much as possible.
A strong vibration or shock that can be felt by the human body must not
be transmitted to the instrument (otherwise the fine adjustment
mechanism might malfunction).
Avoid the vicinity of a heat generating apparatus such as a gas burner,
electric heater or oven in order to prevent the mainframe cover being
heated (beyond 70℃).
Avoid the vicinity of instruments that generate a strong electric field
(such as an electric welding machine, high frequency furnace or pole
transformer).
Avoid a dusty environment (otherwise optical performance might
deteriorate).
The line voltage must be stable and free from a rapid fluctuation
(otherwise noise might increase).
Do not turn on and off frequently electric instruments (stirrer, vibrator,
etc) that are not provide with a noise-preventive device in the same
power line as for the mainframe.
Note: The optical system is very delicate.
And the control unit incorporates high-density electronic
circuit components that function as a computer.
So the above cautions should be observed strictly.
