摘要： A data recorder configured to idle in a power-saving mode until an input trigger signal is received by the data recorder. After the trigger signal is received, the data recorder samples input data sequentially at successive time intervals, and may record the sampled input data into non-volatile memory. The data recorder samples but does not record data from an input if the data have not changed by a predetermined threshold since data for the input was last recorded. The data recorder monitors and identifies an imminent failure in its power supply, and powers down into a power-saving mode after completing the recording of any sampled but incompletely recorded data, as necessary. The data recorder is configured to recover from a brownout and resume sampling and/or recording data. The data recorder is also configured to recover from a blackout and resume sampling and/or recording data.
