15.2.3 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.
15.2.4 Averaging Too Short
The averaging interval is either shorter than the sampling interval or than the sensor reply time.
15.2.5 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 )

15.3 System Errors
15.3.1 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.
15.3.2 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.
15.3.3 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 transmissions when the
voltage is too low. Please see the section
12.4 C
UTOFF
for more details.
The only way to fix this error is to provide a sufficient power supply.
15.3.4 Transmission Failures
A variety of issues can cause problems with transmissions:
