RetroTek Model 135 Operator’s Manual

 

 

The RetroTek Model 135 is a sensitive dynamic balancing amplifier based upon the Gisholt method of balancing. It may be used on a soft balancing machine for one or two plane balancing a single rotor or for production balancing of a batch of rotors. A single rotor or the first of a production run is temporarily balanced. The amplifier is then setup to permanently balance the initial or all succeeding identical rotors. The panel meter indicates the amount of unbalance in the left or right correction plane. The strobe flash indicates the angle at which the correction is to be applied. The amplifier may be set to indicate either the heavy side for the removal of weight or the light side for the addition of weight and the meter may be calibrated to directly indicate the amount of correction.
