MMA 7260QT POLOLU

Hello, I am having troubles with my accelerometer mma7260qt from pololu. I just want to read the raw data and check if the values are right. I made thiw connection with arduino nano:

MMA 7260QT ARDUINO NANO

vin------------->3V3 GND----------->GND Z-axis--------->A2 GS1----------->3v3 GS2---------->3v3 (for +- 6g ) vin----------->REF sleep-------->vin(on he accelerometer)

The values I get are these:

Z-axis

968 975 933 887 931 886 920 962 918 965 922 954 915 955 903 925 944 951 940 888 942 989 957 914 932 946 927 955 927 905 918 925 917 949 945 897 923

and I think that are wrong. I am new with arduino and accelerometer. Please help
