ASCII Gnnn<CR> Commands the instrument to go to wavelength nnm . For example:
G540<CR> will set the wavelength to 540nm.
ASCII Fxxxx.x<CR> Sets the concentration factor to xxxx.x. For example: F1000<CR> will set the
factor to 1000.
Note <CR> is an ASCII carriage return character. The last three commands provide an output which
can be readily incorporated into most spreadsheet software packages.
