The autotest sequence is immediately stopped if any incorrect condition is 
detected, e.g. excessive Uc or trip-out time out of bounds.

Auto test is finished without x5 tests in case of testing the RCD type A with rated 
residual currents of I

Δn = 300 mA, 500 mA, and 1000 mA. In this case auto test 

result passes if all other results pass, and indications for x5 are omitted.
