protective earth terminal. Do not invalidate protection by using an extension
cord without protective grounding.
Protective Grounding

turning ON the power.
Necessity of 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 hazard.
Defect of Protective Grounding and Fuse
Do not operate the instrument when the protective earth or the fuse might be
defective. Also, make sure to check them before operation.
Fuse

is specified by the instrument. When replacing a fuse, turn OFF the power
switch and unplug the power cord. Never short the fuse holder.
Do Not Operate in Explosive Atmosphere
Do not operate the instrument in the presence of flammable liquids or vapors. Operation
of any electrical instrument in such an environment constitutes a safety hazard.
Do Not Remove Covers

if the power supply is connected. The cover should be removed by
YOKOGAWA’s qualified personnel only.
External Connection
Connect the protective grounding before connecting to the item under
measurement or control unit.
