Description
The
frequency
monitor
signal
(FM)
can
be
transmitted
by selecting
2 types
of signals
below.

This
monitor
outputs
the
same

as
the output
frequency.
The duty is

Monitor
for analog meter
This monitor
outputs
the duty
(t/T)
proportional
to the output
frequency.
Adjust
the variable
resistor
(M.ADJ)
and
the variable
resistor
of
frequency
counter
itself
so that
the meter
is
maximum
at the highest
frequency.
