hi,

what is the procedure for calibration of ADXL213 for angle measurment,

is ther any standard procedure,

 

 

 

also ,

is there any diference in output of following 2 formule

1>       

Acceleration = ((t1/t2) – Zero g Bias)/Sensitivity

Where in the case of the ADXL213

Zero g Bias = 50% nominal

Sensitivity = 30%/g nominal

t2 = RSET/125 MΩ

 

2>    AOUT [g] = AOFF + (Gain × AACTUAL)

          where

                    AOFF [g] = 0.5 × (A+1g   +   A−1g)

                       Gain = 0.5*((A+1g  -  A−1g)/1g
