Problem with getting Raw values from GY-85 IMU

[wiki.]

Hello,
i am at the very first stage.i am just taking raw values from the accelerometer of GY-85IMU,it uses ADXL345.
But the problem is that it is giving me same value on Z-axis in every orientation.
This is the code:

#include <ADXL345.h>
#include <bma180.h>
#include <HMC58X3.h>
#include <ITG3200.h>
#include <MS561101BA.h>
#include <I2Cdev.h>
#include <MPU60X0.h>
#include <EEPROM.h>

//#define DEBUG
#include "DebugUtils.h"
#include "CommunicationUtils.h"
#include "FreeIMU.h"
#include <Wire.h>
#include <SPI.h>


int raw_values[9];
float conv_values[9];
float ypr[3]; // yaw pitch roll
char str[256];
float val[9];
float values[9];

FreeIMU my3IMU = FreeIMU();
//The command from the PC
char cmd;

void setup() {
Serial.begin(115200);
Wire.begin();
my3IMU.init(true);

// LED
pinMode(13, OUTPUT);
}


void loop() {

for(uint16_t i=0; i<500; i++)
{
my3IMU.getRawValues(raw_values);
Serial.print('\n');
Serial.print("RAccX="); Serial.print(raw_values[0]); Serial.print(" ");
Serial.print("RAccY="); Serial.print(raw_values[1]); Serial.print(" ");
Serial.print("RAccZ="); Serial.print(raw_values[2]); Serial.print(" ");
Serial.print('\n');
Serial.print('\n');

}


while(1){};
}

can u tell me what is the problemm???
