Data Format for the printout is described below. All lines end with a carriage return

<cr> and a line feed <lf>, (0dH and 0aH in ASCII).

Format Output:

The lines will include a heading for each line then the value. A typical output when

weighing is shown below. 8 lines of data are printed including one blank line at the

end.

Note: the Karat unit should reflect the setting of the Alloy parameters, K Ag, K Cu, K

1:1, K m-n or Ko Def.

If the density is of a value that does not allow the karat value to be determined the

printout should have blank values for content and karat. For example
