PROBLEM TO BE SOLVED: To provide a data logger with which it is possible to effectively utilize memory means.SOLUTION: The data logger is configured with a device body equipped with control means, memory means, operation means and output means, and an input unit for latching each sampling data from a channel whose sampling interval is shortest and a channel whose sampling interval is an integral multiple of the former. The control means causes each of the sampling data obtained by starting measurement from an initial set time, with an initial sampling interval defined using a channel of the shortest sampling interval among channels as a reference and the other channels included, to be stored separately in the memory means as memory data, and when the actual measurement start time that is set for each channel of other than the initial sampling interval is reached, the memory data of the relevant channel is deleted, in which way the sampling data on and after the actual measurement start time is stored in the memory means as actual memory data under the original sampling interval.SELECTED DRAWING: Figure 2 |
