the polarities correctly, red is positive and black is negative.
The value in the right side of the first line sets the test duration in minutes. The second line
shows the upper limit of current on the left and drive voltage on the right. After setting the
current and voltage, Press the button for more than 3 seconds to start the process.

You can stop the test at any time by pressing press the button
5>Brushed Motor Drive
You can easily break-in a new brushed electric motor using a variable voltage and running time.
With this function you also can check the motor performance to optimise your power-train.
The break-in process is essential for maximizing the power of a new brushed motors.
New motors have square brushes which press up against the curved commutator.
The goal for the break-in process is to gentle shape the brushes so that they develop a curved surface that fits
snugly against the commutator giving greater conducting surface area and hence lower losses and higher efficiency.
WARNING: Do not operate the motor with anything attached and keep the rotating parts clear of hazards.
