Figure 39: Diagnostic Events Status Register (no active events)
A typical display with two active Diagnostic events is shown below:
I F igure 40: Diagnostic Events Status Register (two active events)
If more than 7 events are displayed, the user can scroll with the joystick UP
and DN buttons to see all indicated events. If the event is not latched in the
Latch Diagnostic Event Register, it may appear and disappear from the
status screen; it will be indicated as long as the actual event is taking
place.

Using the Mask Diagnostic Event Register settings, the user can
individually enable (unmask) or disable (mask) each event. The event is
enabled if an asterisk appears in the brackets to the right of the event
name. If the event is disabled (no asterisk), it will not be processed or
indicated in the Events status Register, even if actual conditions for the
event have occurred. By default, the meter is shipped from the factory with
only one event active: "0 – CPU Temperature Too High". All other events
are disabled. For a typical display with Mask Diagnostic Event Register
selection, see Figure 41:
