7.1.1 Instrumentation Maintenance
The instrumentation requires a minimum of routine maintenance. A few
preventative maintenance steps will optimize battery life and decrease the
chances of datalogger failure.
7.1.2 Batteries
Rechargeable power supplies should be connected to an AC transformer
or unregulated solar panel at all times. The charge indicating diode
should be "ON" when voltage to the charging circuitry is present. Be
aware of battery voltage that consistently decreases over time, which
indicates a failure in the charging circuitry. Smart Weather automatically
programs the weather station to measure battery voltage.
7.1.3 Desiccant
Enclosure humidity is monitored in the WS-PRO2 Enclosure system by a
RH sensor incorporate inside the enclosure. Change the desiccant packs
when the enclosure RH exceeds 50%. The enclosure RH sensor should
be changed every 5+ years.
7.1.4 Sensor Maintenance
Sensor maintenance should be performed at regular intervals, depending
on the desired accuracy and the conditions of use. A suggested
maintenance schedule is outlined below. Log file is for one year of station
use.
1 week
•
Check the rain gage screen and funnel for debris and level.
1 month
•
Check the solar radiation sensor (pyranometer) for level and
contamination. Gently clean with blast of dry hair, soft camel hair
brush, or clean water if needed.
•
Do a visual/audio inspection of the anemometer at low wind
speeds. Worn bearings can cause the wind cups to spin in an
uneven manner and/or make a grinding sound.
