Cancelling and Clearing Alarms
An Alarm is immediately activated when the reading goes below the lower threshold
(low alarm value) or exceed the upper threshold value (high alarm value).
The alarm is then displayed for the time that has been set using the DASH4PRO menu
item
4.1 Warning Time
(page 21).
All alarms checked after every 30 seconds since they were last displayed. If they are
below or above the lower or upper thresholds, then alarm message is displayed again
for each variable.
11.1.1
Cancelling Alarm messages
If you press any button on the DASH4PRO during the time that the alarm is displayed
on screen, alarm message will be cancelled giving the message Alarm Cancelled.
After the 30 seconds from the cancellation, DASH4PRO again check for the alarm
conditions for that variable. If the one of the conditions are met alarm will be shown
again.
11.1.2
Clearing and disabling alarms until DASH4PRO restarts
If any button is pressed and held for more than one second (long button press) then the
alarm will be cleared and not shown again unless it goes through an upper or lower
threshold. Just staying above or below a threshold will not cause it to be displayed
again.
If an alarm is cleared with a long button press twice in succession during a session, then
it will be de-activated until the DASH4PRO restarts. The message “Alarm disabled”
will be shown. Note that this disables the alarm that has displayed and has no effect on
other alarms.
If there are multiple alarms and wanted to cancel them all, you have to cycle over them
to make sure all are displayed.
