MAINTENANCE AND RECALIBRATION
µCache Maintenance
Make sure that the latest version of software is installed for the mobile app and the latest version of firmware is
installed on the µCache. Use the app store for your operating system to confirm that you are using the latest
version of Apogee Connect. The firmware version can be checked in the Settings page in the app while connected
to the µCache.
The µCache unit should be kept clean and free of debris.
If the housing is opened for any reason, extra care should be taken to ensure that the gasket and seating are clean
and the interior stays free of moisture. The screws must be tightened until firm to create a weather-tight seal.
Steps to Replace the µCache Battery
1. Use a Philips screwdriver to remove the screws from the battery cover.
2. Remove the battery cover.
3. Remove the used battery.
4. Place a fresh battery in its place aligning the positive terminal with the + label on the board.
5. Make sure the gasket and seating are clean.
6. Replace the battery cover.
7. Use a Philips screwdriver to replace the screws.
Sensor Maintenance and Recalibration
Moisture or debris on the diffuser is a common cause of low readings. The sensor has a domed diffuser and
housing for improved self-cleaning from rainfall, but materials can accumulate on the diffuser (e.g., dust during
periods of low rainfall, salt deposits from evaporation of sea spray or sprinkler irrigation water) and partially block
the optical path. Dust or organic deposits are best removed using water or window cleaner and a soft cloth or
cotton swab. Salt deposits should be dissolved with vinegar and removed with a soft cloth or cotton swab. Never
use an abrasive material or cleaner on the diffuser.
Although Apogee sensors are very stable, nominal accuracy drift is normal for all research-grade sensors. To
ensure maximum accuracy, we generally recommend sensors are sent in for recalibration every two years,
although you can often wait longer according to your particular tolerances.
See individual sensor product manuals for more sensor-specific maintenance and recalibration information.
