This is the answer that LRP person gave to me, regarding
the jumping around voltage :
the Pulsar uses some sort of pulse wide modulation in order to produce the output voltage for the Motor Run-in function. Therefore you need a proper device to meassure the output voltage exactly. A digital voltagemeter without TRMS (True Root Mean Square) algorithm will display wrong voltages. Same with low standard analog devices. They need the right meassurement method to meassure PWM signals properly.
To cut a long story short. You canīt meassure the output voltage of the Pulsar Motor-Run-in function with every voltage meter, BUT you can believe the voltage, shown in the Pulsar display. So donīt worry about this too much.
Kind regards /Mit freundlichen Grüßen
What do you think folks.. ???
Make sense to me....
