14.2.3.
Sampling Too Short
This happens when the sensor response time is longer than the sampling interval. SDI-12
readings are a good example: if a sensor requires 10 seconds to produce a reading, and the
sampling interval is 10 seconds, this error gets set.
14.2.4.
Averaging Too Short
The averaging interval is either shorter than the sampling interval or than the sensor reply time.
14.2.5.
Bad Setup
This error is recorded to indicate one of the following:
The equation processor reported an error (could be a divide by 0 or syntax error)
A meta measurement referenced an inappropriate measurement
The SDI-12 Command was set to an invalid value
The SDI-12 sensor did not provide enough data values in the result (check
SDI-12 Param
)

System Errors
14.3.1.
Recording Off
If recording is turned off, the station is not collecting data. That is why this condition is
considered an error. This error persists until recording is turned on.
14.3.2.
Time Not Set
This error is noted when the system does not have valid time. This error can only be fixed by
setting the clock or waiting for the system to get network time.
The system has an RTC (real time clock) backed by an internal battery. The clock is set at the
factory. The RTC keeps ticking even if the main battery is removed. This means that the station
should not forget the correct time when it loses power. The battery life is more than five years.
14.3.3.
Battery Low
The system considers any battery voltage below 9.00 V to be an error in an effort to indicate
that the battery needs to be changed. The system will not make any measurements or
t
ransmissions when the voltage is below this value. The value can be changed via the “Cutoff
System Low” command.
The only way to fix this error is to provide a supply of more than the
cutoff voltage.
14.3.4.
Transmission Failures
A variety of issues can cause problems with transmissions:
Two or more consecutive transmissions failing cause an error.
If more than 25 percent of total transmissions fail, an error is flagged.
If no measurements are set up to be included in the transmission data, the system flags
an error.
14.3.5.
Hardware Failure
This error is recorded if any hardware issues were noted since boot up. The errors will also be
placed in the log. Every hardware error has a code logged with it. A hardware error usually
