Troubleshooting
Description of Problem
Explanation/Recommendation
The display shows “SENSOR
TIMEOUT” all the time
This message indicates that the HydroSense II has not received a
response from the sensor. Check that the connector is mated correctly,
the pins are clean and that the connector has not been damaged. If this
problem persists, please contact your local agent.
The display shows an error “NO
GPS LOCK. STORE ANYWAY?”
whenever I store data.
This is a warning to indicate that the GPS has not achieved
synchronisation with the GPS satellite network. This may occur
because the GPS has been turned off, does not have a clear view of the
sky or simply has not been turned on long enough to achieve
synchronisation. As a result, the data will be stored without positional
information and the date & time information may be inaccurate.
This is only a warning and may be ignored if the cause is understood.
Sometimes when take a
measurement the volumetric water
content is displayed as “---”.
“---” is displayed to indicate that the water content sensor was unable
to determine the volumetric water content for these soil conditions. It is
recommended to try a few more times or try another position close by.
For extreme or special soils, period can sometimes be used in
conjunction with a soil specific calibration to yield reasonable results.
The main screen shows “GPS off”
in the bottom bar.
This indicates that the GPS has been turned off in the configuration
menus. Please refer to the GPS submenu to find the GPS power
control.
On the display of my HydroSense
II, I can see the battery icon, the
Bluetooth icon and the GPS icon,
but there appears to be an icon
that never appears.
The icon that is not appearing is the Bluetooth connection icon and it
only appears when the HydroSense II is paired to a computer and there
is an active data connection between them. This happens when
collecting data or changing configuration settings. Generally when
using the computer to collect data from the HydroSense II, focus is on
the computer screen and not the HydroSense II display, so you may not
notice this icon.
