There are situations where the expression '''([0-9]*\.?[0-9]+([eE]?-?[0-9]+)?)''' is not giving the wanted result. For example "C1:PAVA RMS,16.4E-3 V,OK", when using the expression the result will be 1 instead of 16.4E-3. In the given situation the expression ''',([0-9]*\.?[0-9]+([eE]?-?[0-9]+)?)''' will give the correct result. Why does this give the correct answer? When searching for the correct value there is a search for ",[value]" instead of "[value]". | There are situations where the expression '''([0-9]*\.?[0-9]+([eE]?-?[0-9]+)?)''' is not giving the wanted result.

Second Value[edit]
There are situations where the expression ([0-9]*\.?[0-9]+([eE]?-?[0-9]+)?) is not giving the wanted result. For example "C1:PAVA RMS,16.4E-3 V,OK", when using the expression the result will be 1 instead of 16.4E-3. In the given situation the expression ,([0-9]*\.?[0-9]+([eE]?-?[0-9]+)?) will give the correct result. Why does this give the correct answer? When searching for the correct value there is a search for ",[value]" instead of "[value]". Why is the "," not in the ()? Because we want RadiMation® to find the value not the value with a "," in front of it.
