ADC bit and Changing the full scale in Serial 6-Axis IMU Module

Hi,

I am little bit curious about "Serial 6-Axis Accelerometer/Gyroscope Module for Arduino - DFRobot" product. First, i want to know about the total ADC bit in this sensor. Because, there is no information about the total ADC bit in the specification. To see the product, just click on it.

Second.. Please see the code below, this code can be obtained in DFRobot_WT61PC library. I believe that 16.000 is the used full scale, the 9.8 is the gravitational acceleration in m/s^2, and the 32768.000 is the maximum ADC bit used to read the -16 to +16 scale. Then, the result of 16.000 / 32768.000 is the sensitivity in g/bit. Is it right or not? Please correct me if I wrong.

Third.. Is there any way to change the full scale on this sensor? Example: change the full scale from 16.000g to 2.000g.

Best regards and thank you,

Octa Rudin
