Logs Alignment Data Over Extended Periods of Time The EUCLID system can also be used to acquire and store alignment data over long periods of time. By using the EUCLID system with the computer, a machine or a process can be continually monitored for up to four days. The EUCLID system's data logging function can be used to monitor and correlate movement with temperature, time of day, traffic or even the tides. Simply attach the targets to the structure and let the computer store alignment data to a file. A permanent record is available for QC or archival purposes.
