Troubleshooting Guide

If you've installed your Weather Station and find that despite careful attention to detail, it does not work as

expected. The following notes may assist in getting your Weather Station to work.

Nothing appears to work.

Check that the power supply is turned on at the wall socket. Check power cable correctly plugged into the

Junction Box. If the Direction lamps are illuminated, then the power to the instrument is correctly wired and

working.

Wind Direction wrong

If Wind Direction gives the wrong reading, check that the wind sensor has been mounted to point North. If the

Northerly and North East wind direction lamps are permanently lit, then the wind sensor is not connected to

the instrument or is incorrectly wired. Note that if the wind sensor is incorrectly wired then neither wind speed

nor direction will work.

Wind Speed not working

Check anemometer cups are turning freely and if so that wiring is correct (particularly the blue wire from the

Wind Sensor) and the cable not damaged.

Barometer showing incorrect pressure

The barometer may need adjusting to the pressure at your location. First obtain a pressure reading from a

reliable nearby source such as an airfield or local Met Office. Having done this, locate the adjustment screw

visible through the back panel and using a small screwdriver turn the adjusting screw until the pressure

reading is the same as that obtained locally. Do not attempt to turn the screw more than one turn in either

direction.

Temperature reading inaccurate

If you suspect the temperature reading to be inaccurate, please ensure that the thermometer with which you

are comparing is accurate.

If the temperature reading is only 1 or 2 degrees out, then the display can be recalibrated as follows:

Remove the display from the wall by lifting the unit and pulling forward.

At the back of the display there are three small "dip" switches next to the 8-way cable plug. Turn switch "1" to

the other position. The display should now enter its temperature calibration screen shown in °C. Now use

buttons A & B to increase or decrease the temperature respectively. Switch the "Dip" switch back once the

correct temperature reading has been reached.

Temperature display locked on a fixed temperature

The display may have locked up during installation. Other indications are that none of the buttons located at

the side of the instrument will have any effect on the display. This can sometimes happen and can usually be

corrected by disconnecting the power supply from the mains and leaving for two minutes before reconnecting

again.

Rainfall not being displayed

Check that "Dip" switch 2 has been activated on the rear of the display.

Rainfall not being measured

Check that the rain sensor has not become blocked with leaves or bird droppings etc.

Check also the sensor is mounted horizontally.

Very slowly put 5mL of water (a medicine spoon) into the Rain Sensor and check water is coming out of the

bottom tube a drip at a time. If so, this should give a reading of approximately 1.00 mm on digital display

(ensure reset before starting).

If it still does not work, check that the sensor has been wired correctly and the cable is not damaged. If wired

underground check that rodents have not chewed through the cable.
