Incoming pulses can be multiplied by a
selectable pre-scale factor. This is useful for
converting pulse rates from target wheels,
flow sensors and measuring devices to the
required scale factor, or for conversion to the
appropriate engineering units.
Press D to navigate the cursor across the digits.
Press U to change the value of the digit with
the cursor underneath.
Press R to confirm the Input Pre-scale
Factor.

The channel input signal is sampled at a predetermined interval.
The value of an Analogue signal is averaged
and updated at periodic intervals and the
update period is adjustable. A low setting
will give rapid reaction to the input signal
and higher settings may be entered where
damping of a fluctuating input is necessary,
or simply as a means of applying a delay to
the input. This is particularly appropriate in
electrically noisy environments.
In the case of a Pulse/Frequency input, the
microprocessor determines the frequency by
counting or Sampling the number of pulses
that occur during a timed period.
