  • Page 2: General Information

    General Information General information Introduction Your Pro-Master is a professional motor testing device and a high-quality battery charging unit. The device is equipped with modern technology and so delivers utmost precision. This makes Pro-Master equally suited for hobby and industrial applications.

  • Page 3: Safety Precautions

    Do not charge the lead-acid battery during a motor-check !!! If you use a big automotive battery and check motor with 11 turns or less the power limit of the Pro-Master will be reached. (Pro-Master message: „High Power“). In this case you must use a battery with less capacity.

  • Page 4: Pro-Master Operating Instructions

    If you use a big automotive battery and check a motor with 11 turns or less the power limit of the Pro-Master will be reached. (Pro-Master message: „High Power“). In this case you must use a battery with less capacity. Don´t try a bigger one !!!!! For the battery charging function you can instead use a stabilized power supply delivering 5-10 amperes.

  • Page 32: Example Of Setting Motor Timing

    Robitronic Pro-Master Manual PC Software Example of setting motor timing To find a motor's optimal timing point, you need to run motor checks with different timing settings and compare these. The timing should be modified from the default setting in at most four steps. If you check more than four settings, there is the danger that the motor data will change too much due to heating of the motor or changes in the brushes and the collectors.
  • Page 33 Robitronic Pro-Master Manual PC Software Next the motor timing is retarded by a half step. Press function key [F4]. The motor check begins. Curve1: Timing 1.0 (solid line) Curve2: Timing 1.5 (dotted line) The result is a reduction in RPM, power and efficiency.
