ScreenElementDescription.svg Reset The reset code that needs to be send to device. When left blank no command will be send.
ScreenElementDescription.svg Init The Init code that needs to be send to device. When left blank no command will be send.
ScreenElementDescription.svg Get Id The code that needs to be send to device to get the identification back. A common used SCPI command is *IDN?. When left blank no command will be send.
ScreenElementDescription.svg Trigger and Reading
ScreenElementDescription.svg Trigger The command need to trigger the measurement. A common used SCPI is *TRG. When left blank no command will be send.
ScreenElementDescription.svg Read Back In the read back the returned information is defined. This is different for every type of machine there for RadiMation® used regular expressions to understand the format. A good regular expression for finding the first number in scientific notation in a text is: 
([+-]?[0-9]*\.?[0-9]+([eE][+-]?[0-9]+)?)

For more possibilities see the example section

ScreenElementDescription.svg Trigger and Reading
ScreenElementDescription.svg Minimum value The lowest value that can be measured with this device. The value must be the same as filled in the EUT window.
ScreenElementDescription.svg Maximum value The highest value that can be measured with this device. The value must be the same as filled in the EUT window.

U_L_N 325 (-?[0-9.,Ee-]+) 325 Takes the first number.
I_L1;12.34 ;(-?[0-9.,Ee-]+) 12.34 Takes the first number after ";".
THD_U_L1;;14,5 ;;(-?[0-9.,Ee-]+) 14.5 Takes the first number after ";;".

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.
