Examples

## Not run: 
# define bitweight for 0.5 inch sensor with Rg = 2.2k
sensitivity = 22.014e-6 # 22.014 uV/Pa
Rg = 2.2 # gain-setting resistor value in kilo-ohms
gain = 1 + 49.4/2.2 # amplifier gain
A2D = 0.256/2^15 # volts per count in analog-digital converter
bitweight = A2D / (gain * sensitivity) # conversion from counts to Pa (Pa/count)

# convert files from two Gems (SNs 000 and 001)
Convert('raw/000', bitweight = bitweight)
Convert('raw/001', bitweight = bitweight)

## End(Not run)

## Not run: 
ReadGem(0:1, 'raw/000') # read files raw/000/FILE0000.TXT and raw/000/FILE0001.TXT
