The digital multi servo tester offers three modes to check servo motors or ESCs by connecting it to a battery or power supply. It can connect to up to three servos at the same time, and you can also connect up to three ESCs to test and compare their reaction time.
The three modes are Manual (move the servos and check throws by turning the knob), Neutral (the servos are set automatically to the neutral position) and Auto (the servos move to their extreme positions automatically).
The listing describes it as a brand new high-quality tester with LED indicators, and gives an operating voltage of DC 4.8 to 6V, an output signal of 1.5ms plus or minus 0.5ms, a weight of 12g and dimensions of 6 x 4 x 3cm.
Three test modes: manual, neutral and auto.
Manual mode: turn the knob to different speeds and check reaction time.
Neutral mode: servos go back to the neutral point.
Automatic window-wiper mode: servos swing at the largest angle possible.
Multi-channel: up to three servos, or up to three ESCs.
LED indicators: built in.
Small and light: 12g.
Servos and ESCs are controlled by a repeating pulse whose width tells the device what to do; about 1.5 milliseconds is the centre or neutral position, with roughly 1.0 and 2.0 milliseconds at the ends. A servo tester generates that pulse itself, so you can check a servo or ESC without a receiver, a transmitter or a flight controller.
That makes a tester useful for finding faults. If a servo moves smoothly on the tester but not on your model, the problem is in the receiver, the wiring or the flight controller. If it jitters or stalls on the tester as well, the servo is likely worn or damaged.
Always power the tester within its rated voltage range and keep servos free to move, because a servo pushed against a stop will draw a lot of current and heat up.
