6	6	The "Measurement File" or "m-file" is an ASCII text, human readable, JSON format file which holds information pertaining to a measurement or group of measurements. In general, a measurement file will hold all data from sensors sampled at a particular time (i.e. - measure a group of five thermocouples at 11:30am on Dec. 1, 2012). However, it is not limited to this, as one could group a single sensor, or even a group of sensors, over an extended period of time. The format of this file is a JSON array of JSON objects containing information about the sensor and it's measurement.
