Readback example(s)[edit]
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. By leaving it outside the "([expression])" it does search for it but it is not part of the decoding of the value.
