This great little device can be used to test functionality and repeatability of servos. Just apply 4.8V - 6V and use the adjustment knob to move the servo, dependent on the test mode.
The device also can be used as a signal generator for Electronic Speed Controllers (ESCs) then you can test your motor system without using a transmitter and receiver.
There are 3 modes to check servos or Electronic Speed Controllers (ESCs):
1. Manual mode: turn the knob with different speed, check the reaction time.
2. Neutral mode: make the servo go back to the neutral point.
3. Automatic "window wiper" mode: make the servo swing back and forward.
It can connect 1-3 servos simultaneously so you can test consistency across them.
You can also connect 1-3 ESCs to test and compare their reaction time respectively.
Great for testing the servos from CCPM RC helicopters or RC Planes
