PB-188P : It's a new and surprising product with multi-functions. The inside generates electricity naturally and affords the track of the rotor to show dynamic running subtitle. The highest RPM is also shown. Instructions : According to the direction of the arrows on the rotor and the method of starting up PB-188, accelerate the ball until one ring of light shines (over 6,000 RPM). Then relax the hand skillfully and wait for the words or number to appear when the LED rotates to the bottom of the ball.
Generally speaking, the content of words is fixed, and the words will appear only twice between 6,000 and 8,000 RPM. At the rest of the time (over 6,000 RPM), the LED will show the highest record of RPM. Every time when the new highest RPM record surpasses the original one, the LED will twinkle and show the new RPM number. However, when the speed is less than 2,500RPM, the highest RPM record will be cleared off. Besides the above, it has one more function: showing the number of revolutions within 30 seconds. Please take the product manual as reference.
