3. Function
The battery powered data-logger is meant for recording data.
The following signals can be directly connected to the unit:
- 0...1 V
- 0...20 mA
- 4...20 mA
- Pt 100
- Potential free contact or 5V DC TTL peak
The value of the input signal can be read off, to scale, in the
correct engineering units on the built-in display.
Engineering units and information text can be individually
written onto the space available on the front of the unit.
It can be selected whether the collected data is to be stored as
instantaneous or min/max/average values in the built-in
memory system (continuously or only on active set point alarm).
Every second the measured value is read in.
Min/max/average values are stored in a buffer until the end of
the measurement cycle. At the end of this cycle they are
calculated and stored in the internal memory.
Additionally the digital input records counters (how often was
the contact closed?) or operation times (how long was the
contact closed?).
The software package delivered with the unit analyses the data
and displays it either graphically or tabular.
All data-logger parameters are set up using this software
package.
