The instrument is operated using a simple interface on the controller on the side of the system. The user can start or stop the combing rotation, and adjust the combing rotation speed from 15 to 35 rpm (combing frequency from 1 Hz to 2.3 Hz). An emergency STOP button is present (in red) to stop the combing in case of a hair swatch being stuck or tangled. A RPM indicator displays the speed of the combing rotation.
Each slot is fitted with up to 4 evenly spaced and easily replaced combs. The swatch mounts are attached to a height-adjustable bar for maximum adaptability. Hair swatches can be easily removed and attached with the thumb screws mechanisms.
