barfield DPS1000 - Appendix B: Operating Limits; Aeronautical Limits Profile

Appendix B: Operating Limits
The DPS1000 comes with 2 pre-defined sets of operating limits: the default limits profile and the
max limits profile. The unit also includes limits files for each of the three operating modes:
Aeronautical, Pressure units and EPR. Each of these three operating modes contains a default
limits profile and a max limits profile. The values for both limits profiles are stored in an R/O “read
only” file. The Test Set will first power up and initialize with the default limits profile. If the customer
changes the limits to the max or a custom limits profile, the Test Set will power up using the last
profile selected.
The following tables represent the default and max limits profile values included in the DPS1000:
