DME 7.8 DME 7.80 once. It can now be either "present" or "not present". Every time the fault status changes from "not present" to "present", the number in the frequency counter is increased by 1. A rather high value in the fault frequency counter may therefore indicate a loose contact. It should be noted that the environmental conditions apply only to the first and the last occurrence of each fault.
