Res.unit
8 characters;
Result unit
Designation of the result unit for final result (text-only entry).
If
#
is entered as the first character, the result calculated with the
formula is automatically provided with a prefix (m,
µ
, n, etc.)
(e.g. 5.64
µ
g/L for 5.64ú10
–6
g/L).
On the transfer of standard formulae with the softkey
method>
, either
#g/L
or
#g/g
is entered in this field, depending on the
entry of
S0
(see Standard formulae).
Sign.dig.
1...5; 5
Significant digits
Number of significant figures for the final result.
