At departure, the train master actuated a security switch to arm the SoMat. The same switch was turned off by the train master at Atlanta. The versatility of the Digital Module option allowed partitioned data records for round trip operation. A separate switch was dedicated for the northbound run. These words are checked against data mode trigger statements defined in the setup file.
Results are report ready immediately at the end of the test.
On-line processing reduces the memory appetite of the SoMat. It also eliminates the need to record data to one media and then convert to another before analysis begins. It shrinks design cycle time. It decreases operator effort. Plus, in the unfortunate event of a spoiled test, it signals an immediate need to repeat.
