The stroking rate set in "Manual" operation results in the max.
stroking rate in "Contact" operation. If no frequency reduction is
desired the max. stroking rate is to be set in "Manual" operation
before switching over to "Contact" operation.
This function enables the number of pulses received to be divided by a
factor of 0.01 to 1.00 or multiplied by 1.00 to 9999.
