Figure 3. RPM-Converter Setup Page
Select the engine type and number of pulses per crank rotation. Then press the setup button.
Follow the instructions provided on screen. After the setup is complete, the LED on the RPM-
converter should light up steadily. To test your setup, press the 'Test' button. The LED on the
RPM-Converter should light up for about 4 seconds.
To test your sound output, connect the regular speakers back to your computer. Then select '4-
Stroke', uncheck 'Waste Spark', select Ignition Pulses and set the number of Cylinders to 12.
Then press the 'Test' button. You should hear a loud tone of about 440 Hz (Middle A). The output
frequency is set to simulate 4400 RPM for the selected engine type.
5.2 Auto-configuration using your engine
- Connect and power up the LM-1 and RPM-Converter as described in Chapter 4.- Make sure the
Indicator LED is lighting up steadily at 2000 RPM.
- Press and hold the Setup button on the RPM-Converter until the Indicator LED on the RPM-
Converter blinks rapidly.
- You have now 10 seconds to rev up your engine to 2000 RPM while the Indicator LED blinks
rapidly.
- Hold the engine at 2000 RPM ( +- 200 RPM) while the Indicator LED blinks. When it starts to
blink slowly it is taking measurements.
- After a total of 15 seconds the Indicator LED will light up steadily.
- Relax, you are done.
The RPM Converter accurately tracks RPM signal up to a limit of 10230 RPM. If your engine is
expected to rev higher than 10230 RPMs in operation, hold the engine at 4000 RPM (+- 400
RPM) instead of 2000. The datalog will still be showing 0-10230 RPMs, just double the values in
the data log or change the setup using the custom setup procedure as described in the LM-1
manual. This procedure works only for pulsed rpm signals of up to 6 pulses per crank rotation.
