Hours at failure (first three digits) "YYY"2. Hours at failure (next four digits) "XX.XX"3. Worst case reading4. Clearing hours (first three digits) "YYY"5. Clearing hours (next four digits) "XX.XX"The hours at failure and clearing hours would be interpreted as "YYYXX.XX", providing a maximum of 99,999.99 hours and an accuracy level of 0.01 hours or 36 seconds.The display will roll over from Level Six to Level One on the error occurences reading, and from Level Five to Level One on the failure information readings.Exit from this mode by activating all three touch buttons simultaneously.Diagnostic Data 2
