End-to-end testing
Testing is very important, so you can be confident that the alarms are correctly
set up. You should do it twice
– once before you take the logger to site, and once
after installation. End-to-end means you are simulating the whole alarm
process, from the measurement at the sensor to the receiver of the alarm.
You should simulate an alarm condition at the sensor, which may be a bucket of
water for a level sensor, or in this case a cup of warm water.
Now wait until the alarm is triggered
– you can tell because the LED on the logger
will start flashing blue rapidly as the modem is switched on. This will start very
shortly after a measurement is taken, and for 5m recording, this happens on the
“cardinal points” of time – look at your PC clock for times like 10:05, 10:10, etc,
assuming you used this PC configure and reset the logger.
Once the logger has stopped flashing, you should receive the alarm email or
SMS message almost immediately.
Look on Timeview, on the List Latest page. The alarm should appear at (1),
while the thumbnail plot for the should will show the alarm as a small red circle
(2).
View the alarm to check the contents and delivery. You can see the alarm time
stamps (1), the message recipients (2) and (for SMS messages) a delivery report
to confirm if the message has been received by the recipient’s phone.
