Frequency of the pulse train is equal to the speed of the machine in RPS(Rotation per second). Dividing RPS/60=RPM. You need a frequency counter to measure the frequency of the pulse train in DS1104.
GOOD LUCK...

Please try a resistor on output of ir speed sensor because i had also faced this.This type of problem are arised due to some kind of load variations, weather the voltages are not complete or there is something improper wiring in a practical circuit.
