These output formats are essentially the same except that the Dual format saves the data of a dual window measurement. The import process into MultiCalc is the same for both formats. In MultiCalc, every counter protocol has its own auxiliary directory. To evaluate your Tricarb data with one of these methods, copy the file into the corresponding subdirectory in the \0AUX subdirectory. Restart MultiCalc as this software does not rely on the operating system to keep track of the contents of its folders. Then evaluate the data as you would with any other MultiCalc data set.
