Wind Speed/Direction
This sensor requires very little maintenance, however, it does incorporate moving parts
which will eventually wear out. A more detailed maintenance section is provided in the
manufacturers’ instructions manual. Inspect the sensor body for physical damage or
loose parts such as the anemometer blade or the sensor mount. Clean unit with mild soap
and water as necessary.
Temperature sensor
The temperature/RH combination sensor is protected within the aspiration shield and is
difficult to inspect. Look for obstructions within the aspiration shields that will prevent
normal air circulation. A free flow of air through the aspiration shields is important for
an accurate temperature reading. Small insects or bugs might find this sort of
contraption suitable to build the ultimate residence. Insure that the sensor membrane
filter/ mechanical housing, which protects the sensing elements from dust and dirt, is
intact. Replace this membrane as required. Use low pressure air to blow out any foreign
materials. If this does not work, you will have to disassemble the aspiration shields. Do
not spray high pressure water between the aspiration shields, this will cause damage to
the integrated sensor.
Relative Humidity
Follow the same precautions as the temperature sensor.
Pyranometer
Insure this sensor is unobstructed and mounted level. Inspect it periodically and clean
the sensor surface, you might have to use a damp towel to remove dirt or dust from the
teflon lens, then wipe it dry.
Barometer
The barometer sensor is built into the 6200 electronics, thus, it is protected from the
elements. The Barometer vent tube exits out the 6200 enclosure. The vent tube must
remain unobstructed. In cold environment applications, precautions must be taken to
prevent the vent tube from freezing. Clean out the rubber boot that shields that vent tube
from ice. Do not spray high pressure water up into the barometer vent tube.
Rain Gauge
The rain gauge should be checked to be sure no creature has decided to make it a home.
The mounting needs to be secure and level so that the water can easily flow thru the
tipping bucket. This sensor requires very little maintenance, however, it does
incorporate moving parts which will eventually wear out. A more detailed maintenance
section is provided in the manufactures instructions manual. Inspect the sensor body for
physical damage or loose parts. Clean unit with mild soap and water as necessary.
Sondes
The YSI sondes have an extensive manufacturers operational manual that details the
specific maintenance procedures needed. Please refer to the appropriate maintenance
section in your user manual.
