Help my ESC wont stop beeping and i cant calibrate it

[mely]

I purchased an ESC recently when I received it today I tried to use it but it would not stop beeping. I know it's not my battery as I've tested it and it gives enought volts to power my esc, motor and servo tester. The servo tester is also knew so i doubt that its the problem.I've read and looked everywhere online for answers but no one seems to have the same problem. I don't know if anyone can help me but I hope someone can. thanks

see the video below to see my problem.

It looks like you turned the knob on the servo tester completely clockwise before connecting the battery. After you connect the battery have you tried turning the knob completely counter clockwise and letting it sit for a minute?

I agree with Mr NCT in general, with one small change.
I would try turning the knob completely CCW before plugging in the battery. Then if the beeping stops, try turning the knob CW to see if the ESC will respond.

If turning the knob CCW works, I would mark the tester somehow that the position is low throttle.

With many ESC's, if you plug them in at high throttle you enter a programing mode. It sounded like the beeps were changing, which to me indicated the ECS was changing what parameter was being programed. You will need to look at the ESC's documentation to understand the beeps.

The regulator is not calibrated: turn the servo tester knob clockwise to the maximum - connect the battery, after the first squeak of the engine, turn the servo tester knob counterclockwise to the minimum. Or similarly with the equipment..

Why are you not using a receiver to calibrate the ESC? When put into what ever the ESC is going into it will have to be calibrated again.

Do you have the signal wire plugged in the correct way ?

Valid point. You should not use a servo tester to calibrate an ESC as most servo testers knob run from 125% to -125% signal. A transmitter normally sends 100% to -100% to allow for the effect of the trim buttons.

Notice the marking around the base of the servo tester knob. For the ESC to arm and be ready to drive the motor the signal it receives must be at minimum or full anti clockwise in your case. This is a safety feature so that the motor will not start at anything but throttle fully closed. At any other signal level it will not arm and will beep continuously except at maximum signal (full throttle) or clockwise which is what you did in the video when the ESC goes into "programme" mode and starts to make a series of coded beeps.
If you do not know the codes then do nothing and simply unplug the power. No programme changes will have been saved.
Set the ESC to minimum signal (throttle fully closed), plug in the power and the ESC will "arm" with a series of beeps which may include a cell count (3 beeps in your case) followed by a single longer beep. The ESC is then "armed". The motor will then run using the ESC knob to control the speed.
Be careful. You really have to restrain the motor or it will seriously 'wind up' its leads as it starts.
