6.7.1 Recorder

The measured values of the linked sensor at the current output are set up as cur-
rent intensity in the Recorder application. The output of measured values is laid
down in the Recorder type, Start value and End value settings.

Explanation
Minimum spacing:
≤ 5 % of the measuring range
(sensor-dependent)
Main variable designates the
actual measured parameter of
the sensor (e.g. pH, oxygen,
etc.).
Adjoining variable designates an
additional measured parameter
(e.g. temperature).
Speed of change of the output
current (mA/s) in the case of
erratic changes of the input
signal.
Current values outside the range
between Start value and End
value are regarded as an error.
The current output reacts as
specified under Behavior at error
(see below).
The current at the output is
limited to the Start value or End
value.
In the case of system errors and
sensor errors, the current output
delivers the fixed current value
that was specified.
Possible values:
0 ... 21 mA.
