How to use a multimeter to confirm if the ESC MOS tube is functioning properly

Measuring the MOS tube of the ESC using the diode setting on a multimeter, the method is as follows:

（1）Desolder all motors and switch the multimeter to the diode position.

（2）Place the "-" test pen on the positive terminal of the ESC's power supply, place the "+" test pen on the motor solder pad of the ESC and measure all the motor solder pads of the ESC.

If the reading of a certain MOS tube is obviously high or low, it means that the MOS tube is abnormal.

（3）Place the "+" test pen on the negative pole of the ESC's power supply, place the "-" test pen on the motor solder pad of the ESC, and measure all the motor pads again.

If the reading of a certain MOS tube is obviously high or low, it means that the MOS tube is abnormal.
