Measurement Setup
Measurement Parameters
To define measurement parameters or sensor char-
acteristics select
Setup > Measurement
.
Measure Period
Measure period is the time interval
in which the data logger records actual measu-
red values (samples) from all sensors.
Statistic Interval
Statistic interval is the time
interval in which the data logger performs a
statistical evaluation of the samples and stores
the results in the memory. The variables a1..an
correspond to the first to nth value of the data
line sent by the first sensor. The variables b1..bn
correspond to the values sent by the second sen-
sor and so further.
Excitation
defines how long the sensor constant
current source (
CC
) is switched on before the
blueberry COMPACT
sends a poll command. Se-
lecting
always on
switches the excitation voltage
continuously on. The
blueberry INPUT Module
requires this setting as it needs a warm-up time
of approx. 5 seconds.
Measurement Functions (Standard
Setup)
To add a new measurement function enter a func-
tion name in the field
Name,
check the required
statistical evaluations and enter the measurement
function. Type
<enter>
to transmit the settings to
the data logger.
Function Names
Variable names may principally contain umlauts
(
ä
,
ö
,
ü
) and special characters like comma (
,
) and
period (
.
). If function names are used as variables
in further measurement functions the first part of
the function name may however only contain the
following characters:
A..Z
,
a..z
,
0..9
,
_
. The second
part, i.e. the part after the first space character is
used as axis label for realtime diagrams. We rec-
ommend to use the following syntax for function
names:
Value (unit)
