Abstract:

A data logging system includes a sensor for monitoring a parameter and a data logger. The data logger includes a first logging mode and a second logging mode. The first logging mode has a low-capacity logging mode adapted to collect data from the sensor at time intervals, identify a start of a data cycle when the parameter reaches a first limit, identify a stop of the data cycle when the parameter reaches a second limit, process the data collected between the start and stop of the data cycle, log the data processed, the data processed having less bytes than the data collected between the start and stop of the data cycle. The second logging mode is adapted to collect data from the sensor at time intervals and to log a portion of the data collected after receiving an event code.
