It comes with a 2X16 characters LCD that is able to display real time measuring value of either sensor or sensor-less brushless motor. Measures : Kv (RPM/Volt) : Show the motor RPM/Volt at a certain throttle power level. U (Volt) : Show the input voltage to motor checker. I (A) : Show the current drained RMP : Show the rotor revolution at a certain throttle power level. Motor timing : Physical endbell timing, usually between 0 and 70 degrees, requires tools to rotate the sensor board. Noise level : Poor assembly motor, inferior bearing and unballanced rotor can generate a vibration. Whenever a motor in air vibrate, it causes compression waves in the air. These waves move away from the motor as sound or noise. Vibration noise of motor is adverse the performnace of motor. By measure the noise level of motors, you can select the less noise motor. The decibel (dB) is a logarithmic unit used to express noise level in the motor anlyser. Phase A, B and C sensor timing : Show the actual timing of three sensor elements.
