You can select the Sample Time (the period over which data is collected and reported) from one of the following choices: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, or 60 seconds. Data is collected internally 10 times/second and is averaged over the selected sample time. The average is displayed on the graph and can be saved to the flash drive. Data is saved to the flash drive every 10 seconds, or at the rate of the data averaging period if it is longer than 10 seconds. The data averaging period is the same as the Sample Time setting. Once the data is being logged to the Flash drive, the Sample Time setting cannot be changed.
IMPORTANT
If power is lost at any time, the instrument should continue data logging when the power is returned. The data files created will have the extension
.rdt so that the previous files are not overwritten.
