6.2 Operating principle
The individual parameters and functions are
divided into three levels for clearer operation of
the recorder:
Basic status
Basic status of the recorder with signal ac-
quisition, recording, indication and process-
ing.
The display shows, depending on setting:
- instrument designation, date and time
(the time can be switched off via the para-
meter parameter level
 display time)
- one channel and its measurement as a
number or bargraph
- or system error messages.
The display can be altered during recording
using the keys
h
and
R
.
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 altered at
the operating level:
- chart speed
- print test
- service print.
A summary of all parameters of the recorder
is given in the Appendix.
