Class Conductivity

Class which holds conductivity experiment data, well actually the recorded data is a voltage ratio. Fills self.data with

• time
• V_ratio: the ratio of excitation to measured voltage: this is what the datalogger records.
• ec: is the V_ratio converted into a conductance (not conductivity! for this the sensor would have to be calibrated with a standard solution)

Parameters:

• filenames (list of strings) - a list of TOA5 Campbell Cr1000 files in chronological order with the same data format.
• reference_resistor (float) - The resistance of the reference resistor used in the experiment in Ohm. Note that for dilution gauging it is not essential to use the correct value for this but it is essential to use the same as in the calibration file. (default=1)
