When the instrument is in stand-by mode, the Pwr LED is orange. When
the instrument is powered-on, the Pwr LED is green.
To avoid the possibility of injury or death, you must observe the following
precautions before switching on the instrument.
•
Insert the power cable plug only into a socket outlet provided with a protective
earth contact. Do not negate this protective action by using an extension cord
without a protective conductor.
•
Do not interrupt the protective earth connection intentionally.
The AC power requirements are summarized on the rear panel of the
instrument.
