WARNING
● Use the Correct Power Supply
Ensure that the source voltage matches the voltage of the power supply before turning ON the power. In the case
of a portable type, ensure that it is within the maximum rated voltage range of the provided power cord before
connecting the power cord.
● Use the Correct Power Cord and Plug (Portable Type)
To prevent electric shock or fire, be sure to use the power cord supplied by YOKOGAWA. The main power plug
must be plugged into an outlet with a protective earth terminal. Do not disable this protection by using an extension
cord without protective earth grounding.
The power cord is designed for use with this instrument. Do not use the power cord with other instruments.
● Connect the Protective Grounding Terminal
Make sure to connect the protective grounding to prevent electric shock before turning ON the power.
The power cord that comes with the portable type is a three prong type power 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 grounding wire or disconnect the wiring of the protective grounding
terminal. Doing so invalidates the protective functions of the instrument and poses a potential shock hazard.

Do not operate the instrument if the protective grounding might be defective. Also, make sure to check them before
operation.

Do not operate the instrument in the presence of flammable gas or vapors. Operation in such an environment
constitutes a safety hazard.

S, SOx, etc.) will cause a malfunction.
● Do Not Remove Covers
The cover should be removed by YOKOGAWA’s qualified personnel only. Opening the cover is dangerous, because
some areas inside the instrument have high voltages.

Connect the protective grounding before connecting to the item under measurement or control unit.
● Damage to the Protection
Operating the instrument in a manner not described in this manual may damage the instrument’s protection.
