Installation
Installation conditions
Power requirements
Power supply voltage:
AC100, 115, 220, 230 or 240V
Allowable fluctuation is within ±10% of rated voltage.
Frequency:
50 or 60 Hz
Allowable fluctuation is within ±4% of rated frequency.
Power capacity:
200VA or more.
A capacity of more than 500VA may be required for use with other
accessory devices.
Grounding line:
Grounding line resistance of 100Ω or less is required.
Installation Environment
(1)
Operating temperature: 5~35 deg C.
In order to perform a measurement under the most stable condition, we recommend
that the instrument is used in an air conditioned room of 20 ~ 25 Deg C.
(2)
Operating humidity: 45% ~ 85%.
(3)
Storage temperature: -20~ 60 Deg C.
(4)
Atmospheric environment:
a)
Free from acid gas or alkaline gas and other gases which may corrode metals
significantly.
b)
Free from gases which may dissolve paint such as from organic solvents
(particularly benzene, thinner etc).
(5)
Other general notes:
a)
Avoid direct sunlight (otherwise optical performance might deteriorate or the
housing might become discolored). Avoid installation by a window if at all
possible.
b)
Vibrations or shocks strong enough to be felt by the human body must not be
transmitted to the instrument (otherwise the fine adjustment mechanism might
malfunction).
c)
Avoid installation in near heat generating apparatus such as a gas burner, electric
heater or oven in order to prevent the mainframe cover being heated beyond 70
Deg C.
d)
Avoid installation near instruments which generate a strong electric field (such as
an electric welding machine, high frequency furnace or pole transformer).
e)
Avoid a dusty environment (otherwise optical performance might deteriorate).
f)
The line voltage must be stable and free from a rapid fluctuation (otherwise noise
might increase).
g)
Do not frequently turn on and off electric instruments (stirrer, vibrator, etc) which
are connected to the same power line
