Module 5 is the programming for Counter C. For maximum input frequency,
Select the operating mode for Counter C.
When Counter C is reset, it returns to zero or Counter C count load value.
This selects the decimal point position for Counter C and any setpoint value
at the same time for the math to be performed on the display values.

Counter C counts the incoming pulses from Counter A input
as per Counter A mode of operation. The signal is scaled
only according to Counter C parameters.
Counter C counts the incoming pulses from Counter A and B
inputs as per Counter A and B modes of operation. The result
is scaled only according to Counter C parameters. (Example:
If Counter A is set for Count X1 mode and Counter B is set
for Count X2 mode, then Counter C will increment by 1 for
each pulse received on Input A and increment by 2 for each
pulse received on Input B less any effects of scaling.)
Counter C counts the incoming pulses from Counter A and B
inputs as per Counter A and B modes of operation and
subtracts the B counts from the A counts. The result is scaled
only according to Counter C parameters. (Example: If
Counter A is set for Count X1 mode and Counter B is set for
Count X2 mode, then Counter C will increment by 1 for each
pulse received on Input A and decrement by 2 for each pulse
received on Input B less any effects of scaling.)
