4.4. Zero alingment
>0% + < and >0% - < simultaneously (2s):
Setting of the present input signal at the output to zero point (zero-adjustment/ zero-alignment)
By individually pressing the keys >0% +< or >0% -< respectively, an individual fine adjustment
of the output signal / the zero point is possible.
NOTE!
Zero-values are saved permanently 7 seconds after last push button action.
During saving LED blinks red for a short time.
4.5. Filter
Through a low-pass filter, the output signal can be set in 10 stages, from 0.8 to 2000Hz.

4.6. Signal output
DIP-switch explanation:
DIP-switch function:
ATTENTION!
In case of exceedance of the input signal of >-120%, the analogue
output is set to the maximum positive initial value.
In case the input signal lies in the range between -120% and 0%, the minimum
analogue signal is released at the unipolar voltage output and the current output
respectively (
see too 4.7
).
