All users:
Check both the logging and the sampling interval to make sure they are greater than one-minute intervals. For example, with a sampling interval of one second, the HOBO logger is constantly on and there is a constant drain to the batteries. If your application calls for such an interval, you may need to replace the batteries more frequently
While inspecting your logger, if you see corrosion on the circuit board that cannot be removed, contact your local Onset dealer for repair.
UA or U23 series logger users:
Check the desiccant pack to see if it is still able to absorb moisture. The desiccant pack that ships with these loggers is color-coded and will be blue when it is still good, pink when it needs to be reconditioned or replaced.
U23 users only:
If you have a black O-ring installed around the battery holder, remove it and contact your Onset representative.
Micro Station Users:
Check the desiccant pack to see if it is still able to absorb moisture. The desiccant pack that ships with the Micro Station is color-coded and will be blue when it is still good, pink when it needs to be reconditioned or replaced. Please refer to the Maintenance section of the Micro Station Manual for further information on this.
Weather Station Users:
Make sure that the station was set up properly with a 2-inch drip loop of cable below the data logger, and be sure that the duct seal fills the void between the cables and the data logger housing. The duct seal should flare out on the inside of the case to lock it in place. Make sure that you have protected the board from condensation and insects. Please read the Field Setup and Maintenance section of the HOBO Weather Station Manual for further information on this.
U30 users:
Make sure that the station was set up properly with a 2-inch drip loop of cable below the data logger. Check your solar panel for damage/debris. Make sure all charger and battery connections are tight.
