  • Page 2: Operating Principle

    Operating principle Considering the simplest physical generator with a rotating The board net voltage ripple frequency can simply calculated wire winding inside a magnetic field produced by two magnetic by multiplying the alternator RPM with the number of poles poles (one pole pair = north and south) - the output voltage is a (e.g.

  • Page 3: General Description

    The TTL output of the laser instrument is connected via cable to the “Ext. Cal In.” input of the RPM-8000-PRO and delivers one pulse per rotation. (don’t press the “Cal Int” Button for Ext.). By comparing the pulse sequence with the measured pulse frequency, the instrument calculates automatically the relationship between ripple balance and speed.

  • Page 4: Functions And Display

    Functions and display: To battery or cigarette lighter sockets - 12-42V LCD screen Indicates the actual speed or the number of pulses per revolution is indicated by pressing the yellow TTL TTL button button Switches the screen to number of pulses per revolution, as long as the button is pressed.

  • Page 8 Internal calibration using the Cal button: 2.000 When a constant speed of 2000 rev/min is registered by the vehicle tachometer, press the Cal. Int. button until the red LED stops flashing, and remains constantly illuminated. Internal calibration requires that the engine is running at a speed of 2000 rev/min, as shown on the tachometer in the vehicle (ideally calibration should be carried out when the vehicle is being driven, that is, moving).
