Sutron Corporation X-Link Operations & Maintenance Manual, Rev 1.63 5/24/2016 pg. 126
The system missed a scheduled measurement (likely due to measurement
taking longer than
Meas Interval
to complete – e.g. system was told to
measure every 5 seconds even though the sensor takes 10 seconds to finish a
reading
Equations
are enabled and the
Meas Interval
is short (once a second or once
every two seconds). X-Link can take several seconds to compute a lengthy
equation and cannot complete a measurement as quickly.
13.2.3.
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.
13.2.4.
Averaging Too Short
The averaging interval is either shorter than the sampling interval or than the
sensor reply time.
Prior to version 1.46, the error "Bad Schedule" was used to mean either "Meas
Interval Too Short", "Sampling Too Short", or "Averaging Too Short".
13.2.5.
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
)
13.2.6.
Bad Wind Setup
X-Link requires that two measurements to be set up for wind: a speed and a
direction and that the two measurements have an identical schedule.
See
section on wind setup.

System Errors
13.3.1.
Recording Off
If recording is turned off, X-Link is not collecting data. That is why this condition
is considered an error. This error persists until recording is turned on.
