Teledyne T100 Manuale Utente

The analyzer’s test functions can be used to predict failures by looking at trends in their 
values (refer to Table 11-2) and by comparing them values recorded for them at the 
factory and recorded on the T100 Final Test and Validation Data Form (Teledyne API 
P/N 04551) that was shipped with your analyzer.   

A convenient way to record and track changes to these parameters is the internal data 
acquisition system (DAS). Also, APICOM control software can be used to download 
and record these data for review even from remote locations (Section 7.3 discusses 
APICOM).
