E36
When software triggered (low), fall time of 1 ms (Range 6) out of
limits. Possible faults in trailing edge slope control circuit U13, U14
or U302. See Chapter 10.5.
E37
When software triggered (high), rise time of 9.99 ms (Range 6) out of
limits. Possible faults as in E35.
When software triggered (low), fall time of 9.99 ms (Range 6) out of
limits. Possible-faults as in E35.
E39
When software triggered (high), rise time of 10 ms (Range 7) out of
limits. Possible faults as in E35.
