If not, a leak will be detected at V1 even though V1 is leak-tight.
The following applies for the valve 2 test:
If t3 is negative, at least 1s s must be configured.
If the t3 calculation for valve 1 yields a value larger than t3 for valve 2, the value must be con-
figured that was calculated for valve 1.
