Digital Servo Tester ESC 4-Channel

This servo tester is used to test and adjust servos and electronic speed controllers (ESC) without a microcontroller. The four outputs take servo plugs, and the pulse width is set with the rotary knob and shown on the display. Running four servos at the same time requires a supply of 2 to 3 A.
