Measurement wavelength absorbance values are in ASCII encoded floating point
format. Each absorbance value is separated by a space, but in case of minus value, a
minus sign is put instead.
Row1=wells(A1-A12),Row2=wells(B1-B12),….Row8=wells(H1-H12)

“.begin”<8 rows of 12 wells of abs. values>”.end”
Reference wavelength absorbance values are in ASCII encoded floating point format.
Each absorbance value is separated by a space, but in case of minus value, a minus
sign is put instead.
Row1=wells(A1-A12),Row2=wells(B1-B12),….Row8=wells(H1-H12)

The checksum is a two byte sum in ASCII encoded decimal(0-255) of all the ASCII
characters transmitted in the measurement or reference data block. The checksum
does not include the character string “.begin” in the checksum calculations.
The following is an example of both and :
“.begin”
