Case('RS.IntermediateRes' > 5.5;"Intermediate result too
high";'RS.IntermediateRes' * 26.5;"Error occurred") = If the result
"IntermediateRes" is greater than 5.5, the text "Intermediate result
too high" will be written into the result, otherwise the intermediate result
will be multiplied by 26.5. If an error occurs during the comparison
('RS.IntermediateRes' > 5.5), "Error occurred" will be saved as a
result of this operation.
2.4.4.9.2 Error
Dialog window: Formula editor ▶ Operators/Functions
Syntax
y = Error(value)
Gives +1 if the value is invalid (error) or 0 if the valie is valid. This
function can be used e.g. to check variables for their existence or validity.
Parameters
Value
The variable to be tested.
Examples
Error('RS.IntermediateRes') = 0: the intermediate result was able to be
calculated.
Error('RS.ZwischenRes') = 1: the intermediate result is invalid.
Error('DET pH 6.EP{1}.MEA') = 0: the variable for the measured value
exists at endpoint 1,
Error('DET pH 6.EP{1}.MEA') = 1: no variable for the measured value
or no EP exists.
