HOBO U30 Station/RC
T r o u b l e s h o o t i n g
No status indicators are blinking
•
The indicators are very faint under direct sunlight. If no indicators appear to be blinking, shield the
logger from the light and check the indicators again.
•
Check the status in HOBOlink. Make sure the battery power is not too low. There needs to be at
least 3.5 volts for logging to continue and 3.9 volts for GSM communication.
•
The memory may be full. Read out the logger and re-launch.
•
The logger may not have been launched.
I made a change to the Launch or Readout Configurations, but it hasn’t taken place
Any changes you make to the Launch or Readout Configurations will not take effect until the next time the
HOBO U30 Station connects to the HOBOlink. If your connection interval was set to 2 hours, then changes
won’t take effect until the next connection on that 2-hour schedule.
The power has run out
•
Recharge the battery for 12 hours with AC adapter.
•
If it cannot be recharged, you will need to replace the battery. Contact your Onset Authorized Dealer
or Onset Technical Support.
•
NOTE
: The U30 Station uses very durable, high-capacity Flash memory. With this memory, data is
retained even when the battery runs out of charge.
•
Important
: Do not re-launch the logger until the data has been recovered. If, the battery cannot
be recharged and, you are still unable to read out the HOBO U30 Station, contact the vendor that
sold it to you. It may be possible to retrieve the logged data.
Too many calls are being made to HOBOlink
Select a slower connection interval in Readout Configuration. Or, consider turning on “Night Mode,” which
allows you to set up a second, slower connection interval overnight.
Too much battery power is being used
Make sure the solar panel is installed properly and functioning. That should provide enough power to
recharge the battery during the day. Or, use the AC adapter to recharge the battery.
Only some of the installed sensors are logging
•
Check for a loose connection.
•
If using the Smart Sensor Expander board, make sure it is connected to the built-in Smart Sensor
board with the expander cable.
•
Make sure you have not exceeded 100 meters (328 ft) of network cable for all Smart Sensors.
•
Make sure you have not exceeded 15 data channels. Use HOBOware Pro to see a list of all installed
sensors and Analog Sensor Ports in the Launch window. The Smart Sensors are listed in ascending
order by serial number. If more than 15 data channels are connected, the devices with the higher
serial numbers will be ignored and their data will not be recorded.
Data file contains errors
In rare circumstances, the data file may have become corrupted. Contact your Onset Authorized Dealer or
Onset Technical Support.
