Relative Humidity
Relative humidity has an adjustment screw located at the rear of the meter. Obtain the
local relative humidity by using a mechanical or an electronic psychrometer. Adjust the
screw to obtain the same reading on the humidity dial. Make only minor adjustments to the
meter at any one time. Allow the meter to stabilize for a few minutes and then repeat
should more adjustment be required. An agreement of three to five percent RH should be
acceptable for this type of meter.
5.5
Barometric Pressure
The barometer should be adjusted for the station elevation. Obtain the local barometric
pressure by calling the local airport or by listening to local weather forecasts. Adjust the
screw at the rear of the barometer to obtain the same reading. Follow the local readings
for several days and readjust the meter as required. Make only minor adjustments at any
time. Do not use force or turn the screw by a large amount to avoid damaging the
barometer.

MAINTENANCE
Maintenance of the weather station is limited to keeping the display panel clean and free
of dust. Use only a damp cloth and water to clean the surfaces of the display panel. The
sensors should be free of debris and kept clean. The wind sensor should be checked for
worn bearings, damaged cable, and loose hardware. Periodic inspections should be made
to help maintain the accuracy of the data. Each time a reading is made, check the wind
sensor to ensure that it is rotating freely in the wind and there are no major problems.
