Press [ENTER].
⇒
The display starts flashing. Use [
↑
] or [
↓
] to set the low-pass filter between 0 and20.
Press [ENTER] again for confirmation.
Remark:
The low-pass filter damps the measurement value display as well as the analogue output signal. This func-
tion can be used in case of big pressure oscillations.
Basically it is recommended to set a low filter with high oscillations (high frequency) and a high filter with low
oscillations (low frequency).
