Up to eight CM7 Sensors can be used at once, so if you’re looking to use more than
one please ensure they are each set to different Channel IDs (numbered from 1 to 8)
in order to be successfully received by the Display Console. The selected Channel ID
will be shown on the small screen on each sensor, as well as on the console next to the
measurements it’s transmitting. It’s worth noting down the Channel ID and location of
each sensor so that you know where each set of readings is coming from!
The default setting is for switches 1 to 3 to be in the DOWN position, which sets the
CM7 Sensor to Channel 1. The full list of different combinations for other Channel ID’s
can be found on Page 24. If you’re setting up your station with more than one sensor,
please refer to this now.
The fourth DIP switch along is responsible for setting the measurement units of each
particular sensor. If it’s left in the UP position it will measure the temperature in Celsius
(°C) whereas moving it to the DOWN position will prompt the sensor to measure in
Fahrenheit (°F) instead. Be sure to check that this is set as desired before powering the
sensor up in order for it to adjust immediately. If you wish to change this later down the
line, you’ll also need to reset the sensor (by removing and re-inserting the batteries) to
prompt this change to take effect.
Further information regarding the Channel Selector can be found on Page 23 of this
handbook.
Once you’ve checked the channel and units of your CM7 Sensor are set correctly,
power it up by inserting 2 x AAA batteries. The sensor will turn on and begin displaying
temperature and humidity measurements, while also showing the Channel ID it has been
set to. If you’re happy with the units and the Channel ID, you can return the battery
cover and screw this back into place.
It’s best to get your Rain Gauge and CM7 Sensor (or Sensors) powered up before the
Display Console. Doing so should ensure that the sensors are active and received quickly
by the console shortly after it’s turned on, as it will enter a searching phase immediately
after starting up where it will try to find any sensors within range.
