ADC: 2¹⁶counts = 4V Hence, calibration of ADC is 2¹⁴counts/V.

Gain of the AA board, g1 = 0.1

GURALP

Sensitivity = 800 V/ms^-1

2¹⁴ counts/V x 800  V/ms^-1 = 13107200 counts/ms^-1 -----> 7.6294e-08 ms^-1/count

Gain, g2 = 10

Calibration = 7.6294e-08 ms^-1/count x g1 x g2 = 7.6294e-08 ms^-1/count

 STS

Sensitivity = 1500 V/ms^-1

2¹⁴ counts/V x 1500  V/ms^-1 = 24576000 counts/ms^-1 -----> 4.069e-08 ms^-1/count

Gain of the STS electronic breakout box, g3 = 10

Calibration = 4.069e-08 ms^-1/count x g1 x g3 = 4.069e-08 ms^-1/count
