Using the Latch Alarm Event Register settings, the user can individually
enable (unmask) or disable (mask) the latch feature for each event. The
event is enabled if an asterisk appears in the brackets to the right of the event
name. If the event is not latched (indicated by no asterisk), it may appear and
disappear from the status screen. It will be indicated as long as the actual
event is taking place. By default, the meter is shipped from the factory with
the latch feature disabled for all events. A typical display with Latch Alarm
Event Register selection is shown in Figure 36:

settings, the user should select the desired event using the joystick UP and
DN buttons, then pressing the RIGHT button. The asterisk will appear in or
disappear from the brackets to the right of the corresponding event. The
asterisk means that the latch feature is enabled.
