Connecting the Power Supply

Before Connecting the Power Supply
To prevent electric shock and damage to the instrument, follow the warnings below.
• Make sure that the power supply voltage matches the instrument's rated supply voltage
and that it does not exceed the maximum voltage range specified for the power cord.
• Connect the power cord after checking that the power switch of the instrument is turned
OFF.
• To prevent fire and electric shock, only use a power cord supplied by YOKOGAWA.
• To avoid electric shock, be sure to ground the instrument. Connect the power cord to a
three-prong power outlet with a protective earth terminal.

ground the instrument, do not use the instrument.
