19. Operation
Before the Microwave Converter is plugged in,
all
protective earth
terminals, extension cords, auto -transformers, and devices connected
to
it
should be connected to a protective earth grounding socket. Any
interruption of the protective earth grounding will cause a potential
shock hazard that could result in personal injury.
Before the Microwave Converter is plugged in, it must be set to the
same line voltage as the power source or damage to the instrument
may result.
The HP 11 793A Microwave Converter is designed to be operated remotely by the measuring instrument
in its frequency offset mode. Operation of the Microwave Converter is, therefore, under control of the
measuring instrument.
