Safety Considerations
Although this instrument has been designed in accordance with international
safety standards, this manual contains information, cautions, and warnings
which must be followed to ensure safe operation and to retain the instrument
in a safe condition. Service instructions, and adjustment procedures requiring
removal of the instrument cover, are for use by service-trained personnel
only. To avoid dangerous electric shock, do not perform any servicing or
make any adjustments with the cover removed, unless qualified to do so.

BEFORE APPLYING AC POWER, THE INSTRUMENT AND ALL
PROTECTIVE EARTH TERMINALS, EXTENSION CORDS, AUTO
TRANSFORMERS, AND DEVICES CONNECTED TO THE

EARTH GROUNDED SOCKET.
ANY INTERRUPTION OF THE PROTECTIVE GROUNDING
CONDUCTOR INSIDE OR OUTSIDE THE INSTRUMENT OR
DISCONNECTION OF THE PROTECTIVE EARTH TERMINAL
WILL CAUSE A POTENTIAL SHOCK HAZARD THAT COULD
RESULT IN PERSONAL INJURY. INTENTIONAL
INTERRUPTION IS PROHIBITED.
Any adjustment, maintenance, and repair of the opened instrument under
voltage should be avoided as much as possible and, if necessary, should be
carried out only by a skilled person who is aware of the hazards involved (for
example, fire and electric shock).
