measured quantity (4 characters) and number of decimals. However,
you can also opt for your own setup (
Basic settings - custom
) and enter
the stated items manually. If you need the convert the measured values
to different values using a two-point linear transformation, turn on the
User calibration function (
User calibration
). For example, you can use
it for converting output voltage of sensor to a different physical quantity
or for applying recalculation to the measured values.
Example of user calibration settings for a heat flux sensor with a
voltage output (-50 to +50) mV connected to the voltage input of
the Multilogger (range -60 mV to +140 mV), with a range of the
sensor between -1000 Wm
-2
and +1000 Wm
-2
:
Upper point B: Input value: +50 will be shown as 1000
Lower point A: Input value: -50 will be shown as -1000
In the next step, set alarms for individual measured quantities. You can
set up to 2 alarms for each measured quantity (
Alarm 1
and
Alarm 2
buttons). Each alarm has to be enabled first (
On/Off
).
Next, select if the alarm occurs upon exceeding or dropping under the
given limit value (
value is greater than / value is lower than
) and enter
this limit. For binary inputs only define the state of the input. Next, you
need to specify the alarm delay (
for the duration of)
, which is used for
eliminating short-term exceeding of the limit value. Hysteresis has a
similar function (
Alarm hysteresis
) - it is used to prevent alarm
oscillation when the measured value fluctuates nearby the alarm limit.
We recommend not to set it at zero. We have hereby completed the
setup for alarm occurrence. Now we just need to specify if the alarm
will be indicated optically on the Multilogger (
Optical signalization -
LED
), acoustically (
Activate internal audio signalization
), by the
ALARM OUT output (
Activate ALARM OUT output
) or by submitting a
warning email (
Send email message ...
).
In some application, we want to calculate other values from the
measured ones, and we want to be able to record them and to create
alarm states. The Multilogger allows this by the means of several
simple mathematical operations (difference, linear equation,
multiplication and division). This way, you can, for example, easily
calculate the difference between the surface temperature and the dew
point of the air. Calculated values can be defined on the section with a
list of inputs and measured quantities by clicking on the given line
button
Calculated - Add.
Their further settings are specified similarly to
the measured quantities (with the exception of the
User calibration
,
which cannot be used for the calculated quantities).
