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
This 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 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 to a Protective Earth Terminal
To prevent electric shock, be sure to connect to a protective earth terminal before
turning on the frame controller’s power. The power cord to use 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 frame controller’s internal or external protective earth wire or
disconnect the wiring to the protective earth terminal. Doing so may result in
electric shock or damage to the instrument.
Do Not Operate with Defective Protective Grounding or Fuses
Do not operate the frame controller if its protective grounding or one of its fuses
might be defective. Check the grounding and the fuses before operating the frame
controller.
Do Not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable gasses or vapors.
Doing so is extremely dangerous.
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. The inside of the frame controller is dangerous because parts
of it have high voltages.
Ground the Instrument before Making External Connections
Securely connect the protective grounding before connecting to the item under
measurement or to an external control unit. Before touching a circuit, turn off its
power and check that it has no voltage.
