The time scale and date display is derived from the file header, where the start time in seconds from Midnight Jan 01, 1970 GMT is stored. It is only as accurate as the PC system clock was at the time the recording was initiated. In order that a 24 display always be available, the first line of the plot is the hour at which recording was initiated, not 00:00 GMT as seen in the LDEO plots. Elapsed time is only as accurate as the crystal on the Dataq A/D board. Our experience with several of the DI-194 and DI-154 devices is that the sample rate is about 300 parts per million fast on all of them, so that about 1.0 seconds per hour is gained. This error can be negated by modifying the header element that stores the sample period to make it shorter by 300 parts per million. If the PC system clock was in error, it can also be corrected by changing the time information in the header. This did not, however, record earthquakes; it only indicated that an earthquake was occurring. 0000384233 00000 n Want to create or adapt books like this?

When more than one channel is activated, multiplexing is accomplished at the 240 samples per second rate, so there will be about 4 milliseconds time skew for each succeeding channel.
