WEB SPEED INDICATION APPLICATION
A newspaper publishing company wants to know the rate at which their
printing press is operating. A fifty-tooth timing sprocket is mounted to the shaft
of one of the press rollers. An MP-62TA magnetic pickup is used to sense the
moving teeth. Direct readout is obtained by setting the time base to a period in
which the number of teeth passing the pickup is numerically equal to the desired
readout. Using the TBIT formula, the following calculations are performed:
TIME BASE INCREMENT = (Display Readout Desired) x (15,000)
TOTAL (TBIT)

DIP switches 2, 3, and 8, are set to “ON”. If the rounding error introduced
above is unacceptable, the display could be scaled up by a factor of 10 and then
a decimal point turned on in the tenths position. The calculations would be as
follows:
TBIT = (Display Readout Desired x 10) x 15,000

Now DIP switches, 4, 5, 6, 9, and 11, are set to “ON”. Also, the tenths
position decimal point would be set to “ON”. (Note: If the time base is now too
long, approximately 5.3 sec. the “FRQ. DBL.” DIP switch can be set to “ON”,
then only half the time base will be necessary.
