  • SF6-Leak Pointer Operating Manual (original version)

    It is necessary to reset the SF6-LeakPointer during a leak search if the unit becomes fully saturated, multiple leaks are present or during the leak verification process. LEAK VERIFICATION If a suspected leak is indicated, verify several times by moving the sensor away from the leak area, resetting the unit and then back to the suspected leak.

    The new_handler may attempt to make more memory available, or terminate the program if it can't. If no new_handler is installed, new instead throws an exception of type std::bad_alloc. Thus, the program does not need to check the value of the returned pointer, as is the habit in C; if no exception was thrown, the allocation succeeded.

    Memory Leaks Definition (Memory Leak) Amemory leakoccurs when all pointers to a block of allocated memory have been lost. Leaked memory cannot be accessed or reallocated; it is useless. Excessive memory leaks may cause the program to run out of usable memory and crash. Memory leaks should always be avoided.
