Self-test duration
The table below shows a summary of the estimated time taken for a self-test
operation with relevant individual modules.
Total duration calculation
Example 1:
Full self-test with 3 units of DAQM907A in one mainframe:
Total duration = Internal DMM + (3 x DAQM907A) = 3 + (3 x 6) = ~21 seconds
Example 2:
Full self-test with 3 units of DAQM909A in one mainframe:
Total duration = Internal DMM + (3 x DAQM909A) = 3 + (3 x 23) = ~72 seconds
Type Area Estimated time (s)
Power-on self-test Internal DMM ~1.5 seconds
DAQM907A ~0.1 seconds
DAQM909A ~3.5 seconds
Full self-test Internal DMM ~ 3 seconds
DAQM907A ~ 6 seconds
DAQM909A ~23 seconds
NOTE
All self-test operations (power-on self-test, or full self-test) will always include
the mainframe’s internal DMM.
