Indoor and remote humidity readings do not match when placed in the same location
Similar to the temperature readings, the console and CM7 Sensor should produce the
same readings if placed next to each other in an identical environment. The sensor
accuracy is +/– 5%, so a difference of up to 10% may still sometimes be possible in these
conditions.
Humidity readings can be calibrated manually if this is preferable – please refer to Page
32 if this would be required.
Display Console screen is faded and hard to read
The contrast of the console will dim as the batteries begin to run down. If the display
of your console is becoming weak, replacing the batteries should solve the issue.
Alternatively, you can purchase a CM7-PA Power Adaptor to provide a constant power
source.
Rainfall readings are lower than expected
If your measured rainfall is lower than you’d expect to see, this tends to be due to the
placement of the rain gauge. Check that rain isn’t being blocked by any obstacles nearby,
as this could easily be preventing rainfall from reaching the Rain Gauge in order to be
measured.
If the Rain Gauge is placed over a metre in height, it’s also possible that the wind could
be affecting your readings. Blustery wind can blow the rainfall in different directions,
meaning it would be less likely to fall into the rain cone as intended. If your rainfall
readings consistently look to be low, assess the height of the rain gauge to determine if
the wind could be a factor.
It’s also worth checking the mechanism itself, located beneath the rain cone. This
mechanism functions like a seesaw and needs to be able to tip fully in both directions
in order for rainfall to be measured. Over time, general debris and insects can find their
way inside the rain cone and physically block the mechanism from tipping completely. If
this is the case, you’ll need to clean around the mechanism to ensure that nothing is in its
way and stopping it from moving properly.
