The Simple version consists of a base with digital button controls with interchangeability of the motors so with a single base you can have all the available versions.
The instrument at power-on with self-diagnosis recognizes the motors and the ability to work. Torque and speed regulation are selected using the UP and DOWN buttons and values selected remain in memory even after switching off waiting for a new setting.
This model has the double pedal (screw / unscrew) available in
all versions as option.
