When a trip occurs, the resultant error information may be viewed either from the
screen
(Program
⇒ Utilities ⇒ Trip History) or from the Monitor screen.
Trip History
The Trip History screen records the system parameters for up to 20 trips. The recorded trips are
numbered from zero to 19. Once the Trip History record reaches trip number 19, the oldest recorded trip
will be deleted with each new record stored (first-in first-out). The Trip # field may be selected and
scrolled through to view the recorded trip information for a given trip number. The monitored parameters
are listed in

will be deleted with each new record stored (first-in first-out). The Trip # field may be selected and
scrolled through to view the recorded trip information for a given trip number. The monitored parameters
are listed in
as At-trip Recorded Parameters (parameter readings at the time that the trip
occurred).
