MPU 6050

My raw accel measurements are to high and i don't know why.

ax ay az gx gy gz 32128 25188 -2560 33 334 177 32160 25356 -2424 53 302 191 32164 25332 -2424 52 283 172 32192 25312 -2556 44 274 160 32132 25304 -2512 54 281 188 32280 25280 -2632 46 284 191 32112 25340 -2560 31 294 174 Sometime ax exceeds the scale and i can't calibrate with offset=-means/8;

I used this code.

#include "I2Cdev.h"
#include "MPU6050.h"
#include "Wire.h"
MPU6050 accelgyro(0x68);
int16_t ax, ay, az,gx, gy, gz;

void setup() {
  Serial.begin(115200);

  accelgyro.setXAccelOffset(0);
  accelgyro.setYAccelOffset(0);
  accelgyro.setZAccelOffset(0);
  accelgyro.setXGyroOffset(0);
  accelgyro.setYGyroOffset(0);
  accelgyro.setZGyroOffset(0);

}

void loop() {
 accelgyro.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);
 Serial.print(ax);
 Serial.print("\t");
  Serial.print(ay);
  Serial.print("\t");
  Serial.print(az);
  Serial.print("\t");
  Serial.print(gx);
  Serial.print("\t");
  Serial.print(gy);
  Serial.print("\t");
  Serial.print(gz);
  Serial.print("\n");}
