The Raw Analog to Digital Probe type is used to see the actual values being red by the Analog to Digital Converters in the loggers. This requires no calibration and the Calibration Offset should be left at 0 and the Calibration Gain at 1. If the channel is set to Low Res it will return numbers between 0 and 255. If it is set to Hi Res it will return readings in the range from 0 to 65535.
The Value from a 12bit AtoD converter will be shifted left 4 times and look like a 16bit number in Hi Res mode
