A zero value of the "Archiving interval" parameter will exclude the set channel
from archiving. This can be preferably used for those channels that are to be
used only for activating SMS alerts.
SETTING THE NUMBER OF MEASUREMENTS
The number of samples from which the final value for archiving will be calcula-
ted using the weighted average method can be set by combining the
Basic Ar-
chiving Interval
and the
Archiving Interval
for each recording channel.
Hydro Logger performs one measurement on all set channels at the interval spe-
cified by the
Basic Archiving Interval
parameter
.
If this parameter is the same as
the Archiving Interval of the measuring channel, this one measured value is sto-
red in memory at the end of the archiving interval. However, if the
Basic Archi-
ving Interval
is set to e.g. 10 min. and the
Archiving Interval of
the measuring
channel to 30 min., the average value calculated from 3 measured samples is
stored in the memory of the instrument every 30th minute
.
The parameter settings can be seen from the following examples of settings:
Example A: Storing the current value measured at the end of every 30th mi-
nute
Basic archiving interval = 30 min
Archiving interval = 30 min
Example B: Store every 60th minute the average value of 6 measurements.
Basic archiving interval = 10 min
Archiving interval = 60 min
Shortening the "Basic Archiving Interval" parameter below 10 minutes results in
faster battery drainage, so set this parameter value judiciously. This note be-
comes less important when using an external power supply.
OVERLIMIT ARCHIVING INTERVAL
The figure shows the triggering con-
ditions for the over-limit archiving in-
terval. Setting it allows you to record
in detail the progress of the incident
on the measurement channel.
The overlimit interval (2 minutes in
the example in the picture) can be
triggered not only by activating an
alarm on the channel itself (in the
picture), but also by an alarm on another set channel (conditions "Every ..."), or
by the start of rain and then, for example, to record minute-by-minute rainfall
and thus actually capture the intensity of rainfall during one rain.
Appropriate setting of the archiving parameters allows, for example, to
suppress the recording of uninteresting low values of the measured variable and
to store only values that exceed the set limit.
