Troubleshooting

Instrument display does not come on.
Make sure receptacle has power by plugging another appliance into it. Check that the transformer is
properly wired into instrument (the leads could be reversed or not seated properly). Check that the
fuse is intact (.75 amp fuse inside the case). Try unplugging the transformer to reset the computer.

Instrument display works but does not read correctly.
Make sure you are displaying the proper scale (English or Metric).

Check that all connectors in the back of the unit are properly seated and that sensor wires are on
their proper junctions and secure (see to Figure 2).

Try unplugging then replugging the transformer to reset the weather station.

Check the fuse in the back of the instrument If it feels hot, replace with a .75 amp fuse available at
most electronic stores.

Humidity reads 0% during the day.
If your humidity sensor is in a plastic box, make sure that is in the shade and has the cover
attached, the humidity sensor is light sensitive (does not apply to pagoda installations).

Rain collector appears to be counting double that of the actual rainfall.
Check that the rainfall count is set on 2.
