Confirming Connections
Once the searching phase has been completed by the Display Console, make sure that
you are receiving the following readings:
•
Remote information from the CM7 Sensor
•
Internal information measured by the Display Console
•
A signal from the Rain Gauge (confirmed by data shown in the Rain field)
If any of these readings are missing, check that the batteries in the relevant part have
been inserted correctly, then reset the Display Console by removing and re-inserting
the batteries.
As long as all of the above sets of information are present, it’s time to situate each part as
desired – ensuring that the Rain Gauge and any CM7 Sensors remain within 100 metre
transmission range of the Display Console.
Installing your Rain Gauge
Rain measurements are traditionally taken at a height of around 45cm from ground
level. Aiming to install your Rain Gauge at this height should help you achieve most-
accurate readings as it will be low enough to minimise interference caused by the wind,
yet high enough to prevent heavy raindrops from bouncing into the rain cone and causing
additional rainfall to be measured.
Most importantly, it’s vital to ensure that the Rain Gauge is exposed and not being
blocked by any trees or surrounding walls. Rain can fall from completely different
angles depending on the weather, so be sure to consider this when looking for a suitable
location. A general rule of thumb is to try to keep the Rain Gauge at twice the distance of
any nearby object’s height – so for example 20ft away from a 10ft tree.
It’s possible that the Rain Gauge may need to be cleared if any leaves or debris create a
blockage later down the line, so it’s also worth considering the accessibility of this part
before installing it permanently. Over time the batteries used inside the Rain Gauge will
run down – replacing these tends to provide a good opportunity to clean the Rain Gauge
at the same time.
