active, (display measuring range limits):
The measuring range is limited exactly to the
input signal. When this exceeds or drops below
it, the indication range limit is displayed. (e.g. for
a humidity of 0 ... 100 % r.H: by dropping below
the limit 0 is displayed, and by exceeding it 100 is
displayed.
When the measuring limits are exceeded (at either end), independ-
ently of the limit settings, the corresponding error message
appears ("Err.1" or "Err.2"). The measuring limits are between
approx. 3.7 and 20.8 mA.
FiLt Filter (filter)
oFF
Filter deactivated
0.1 ... 2.0 Activate the filter in order to prevent the display
from 'jumping' with every small fluctuation and to
suppress single spikes. The larger the number, the
stronger the filtering.
Offset and slope correction
The offset and slope correction is used to compensate for sensor tolerances
and for the fine adjustment of deviations of the transmitter or signal trans-
ducer.
To set the offset and slope correction, carry out the following:
■ While the actual value is being displayed, press key 3 for 2 seconds, until
"oFFS" appears in the display.
■ To set the parameter values, press keys 2 and 3.
■ To save the set value, press key 1. The parameter name will then appear in
the display once more.
■ To switch to the next parameter, press key 1. The name of the parameter
will appear in the display.
