During Recording VFC400-WiFi User Guide 31
During Recording
During normal operation the display shows the most recently recorded temperature. This temperature is
updated at the same rate as the logging interval. The current time is also displayed (in 24 hour format). A tick
symbol
is shown as long as no alarm event has occurred. If an alarm event is registered, a cross symbol
is shown instead of the tick.
At the bottom of the display you can see an alarm day summary, where any days on which an alarm was
recorded are highlighted. The WiFi and cloud connection symbols are also shown.
Following are some sample display screens:
At 1:29 pm:
l Alarm events were recorded 6, 18, 19 & 27 days ago.
The following symbols show on the display:
for the alarm that occurred 6 days ago
for the alarms that occurred 18 and 19 days ago
for the alarm that occurred 27 days ago
l These alarms were cleared by an inspector, as the display
currently shows .
l The current temperature is over the upper alarm threshold, as
indicated by the upper alarm marker (
).
l The duration of this temperature excursion has not yet triggered
an alarm.
At 1:49pm (20 minutes later)
l The temperature has remained above the upper alarm
threshold and has now triggered an alarm event.
l The alarm symbol is shown to indicate an alarm event
occurred
l
The day marker for the current day (
) is shown.
l The alarm event is immediately uploaded to LogTag
®
Online,
where it will show as a notification alert on the dashboard, and
trigger notification emails or SMS messages if configured.
Note the upload arrow ( ) will only show briefly while data are
being transferred to the cloud server
At 1:49am on the next day the
display shows the following:
l The temperature has returned to within the accepted range
(none of the alarm threshold markers are visible), but the alarm
remains present, as it has not been inspected and cleared.
l The day summary has shifted by 1 day as the display time has
passed through midnight (00:00). This means some of the
week symbols have also changed.
The following symbols show on the display:
for the alarm that shifted from today to yesterday. The
today symbol no longer shows.
for the alarm that shifted from 6 days ago to 7 days ago.
for the alarms that shifted from 18 and 19 days ago to 19
and 20 days ago
for the alarm that shifted from 27 to 28 days ago. The
symbol for 3 weeks ago no longer shows, as none of the
alarms occured three weeks ago.
