Power
Sensor.
For
proper system operation,
the
Power Sensor
must
be connected
to
the
Power
Meter using either
the
Power
Sensor
cable supplied
with
the
Power
Meter
or
any
of
the
optional Power
Sensor cables specified in Section

Each
of
these
cables
employs
a sensitivity line
to
enable
the
Power Meter
to
determine the operating range
of
the
Power Sensor and thus,
the
true value
of
the
input
signal.
