Failure to comply with the precautions below could lead to injury or death or
damage to the instrument.
WARNING
• Use the Instrument Only for Its Intended Purpose
The optical measuring instrument is designed to measure the optical
characteristics of light sources and evaluate their performance. Do not use this
instrument for anything other than as an optical measuring instrument.
• Check the Physical Appearance
Do not use the instrument if there is a problem with its physical appearance.
• Use the Correct Power Supply
Make sure that the power supply voltage matches the instrument’s rated supply
voltage and that it does not exceed the maximum voltage range of the power
cord to use.
• Use the Correct Power Cord and Plug
To prevent the possibility of electric shock or fire, be sure to use the power cord
for the instrument. The main power plug must be plugged into an outlet with a
protective earth terminal. Do not invalidate this protection by using an extension
cord without protective earth grounding.
Further, do not use this power cord with other instruments.
• Connect the Protective Grounding Terminal
Make sure to connect the protective earth to prevent electric shock before
turning ON the power. The power cord that you can use for the instrument is a
three-prong cord. Connect the power cord to a properly grounded three-prong
outlet.
• Do not Impair the Protective Grounding
Never cut off the internal or external protective earth wire or disconnect the
wiring of the protective earth terminal. Doing so poses a potential shock hazerd.
• Do not Operate with Defective Protective Grounding or Fuse
Do not operate the instrument if the protective earth or fuse might be defective.
Make sure to check them before operation.
• Reference light source output light (when the built-in light source
specification is -L1)
The instrument has a built-in reference light source for alignment adjustment,
and infrared light is always being output from the optical output connector. Never
look into the optical output connector. Infrared light entering the eyes can cause
severe injury and loss of vision.
• Do not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable liquids or vapors.
Operation in such environments constitutes a safety hazard.
• Do Not Remove the Covers or Disassemble or Alter the Instrument
Only qualified YOKOGAWA personnel may remove the covers and disassemble
or alter the instrument.
Opening the cover is dangerous, because some areas inside the instrument
have high voltages.
• Install or Use the Instrument in Appropriate Locations
• This instrument is designed to be used indoors. Do not install or use it outdoors.
• Install the instrument so that you can immediately remove the power cord if
an abnormal or dangerous condition occurs.
