'CNR4 program

'This program measures CNR4 four-component net radiometer

'This program also measures the thermistor inside the CNR4

'User must enter the sensitivity values for all four probes in the program and save/compile

'prior to downloading it to the datalogger.

'Search for the text string "unique" to find places to enter the sensitivity values.
