PULSES/REV:
Enter the number of pulses per RPM. For engines with an uneven number of cylinders like three cylinder four stroke
engines you can enter values containing fractions (usually 1.5 in this example). Most four stroke engines would generate
one pulse for every two revolutions per cylinder. A four cylinder automotive four stroke engine would thus generate 2
pulses per revolution. A typical Rotax DCDI two stroke engine would generate 6 pulses per revolution. The well known
Rotax 912/914 engine generates one pulse per revolution.
RPM RESOLUTION:
Select the step size between successive RPM values eg. if the RPM value is 4003 RPM and the “RPM RESOLUTION” is
5 then the actual value shown is 4005 RPM.
