- How to get the vibration value?
Please find within the following table which describes your problem. Once selected, mark down the troubleshooting points to follow.
The "g" calculation is based on the vibration level felt on the circuit board, which includes resonance on the thrust stand. For this reason, the measurement is just an approximation and should only be used for comparison purposes.
The accelerometer was added for two reasons: safety and relative measurement of imbalance. The acceleration measurement is a low pass version of the magnitude of the (acceleration vector minus the gravity vector). The accelerometer can be used to shut down the motor if the vibration is too high during a long scripted endurance test for example.
For the axis: Place the ESC in front of you so you can read "RCbenchmark.com Motor Test Tool".
1) The X axis is pointing right.
2) The Y axis is pointing down
3) The Z axis is pointing toward you.
The convention is left hand rule.
Here is the source code that calculates the vibration value from the accelerometer readings. In the code, the accx, accy, and accz variables represent the instantaneous acceleration in g.
float calcVibration(float accx, float accy, float accz){
static float accxlpf = 0;
static float accylpf = 0;
static float acczlpf = 0;
static float vibration = 0;
static byte init = false;
if(!init){
accxlpf = accx;
accylpf = accy;
acczlpf = accz;
init = true;
}
//Acc high pass filter
float accxhpf = accx-accxlpf;
float accyhpf = accy-accylpf;
float acczhpf = accz-acczlpf;
//Instant amplitude deviation
float amplitude = sqrt(accxhpf*accxhpf + accyhpf*accyhpf + acczhpf*acczhpf);
//Vibration filter with different decay/gain factors
#define FILTER 0.9925
vibration = FILTER * vibration + (1.0-FILTER) * amplitude;
return vibration;
}

The load cells are the key components on the Series 1520, 1580 and 1585. If you observe any physical damage on the load cells, please follow this guideline.
Please confirm if the broken connector is on the load cells or on the circuit. If you may have a broken connector on the circuit that allows the load cells to be plugged in, please refer to section 4.1: cross-reference to other types of problem.
This section is only applicable to Series 1580/1585. The calibration process differs on the version of the circuit as well as the software that you may be using. Please follow this guideline if the system keeps indicating that the calibration does not pass after multiple attempts.
The load cell measurement should measure forces with the accuracy specified in the datasheet. If you find that the thrust and torque measured are lower than what the motor and propeller manufacturer advertised, please refer to section 4.1. You can check the accuracy of the tool with the following procedure:
