Operating principle
The individual parameters and functions are
divided into four levels for clearer operation
of the recorder.
Basic status
Basic status of the pen recorder with signal
acquisition, recording and processing.
The display shows:
- the time (can be switched off via the para-
meter parameter level
- and system error messages,
where appropriate.
If there is a system error message, it is
shown flashing at regular intervals instead
of the current display.
Operating level
At this level, signal acquisition and process-
ing remain activated.
The following parameters can be activated
at the operating level:
- chart speed
- print test
