9.4 User settings (optional)
9.4.1 Zero-point calibration
► Select [COF] and set a value between -5% and 5% of the final value of
the measuring range� The internal measured value “0” is shifted by this
amount�
As an alternative:
Automatic adaptation offset (setting range 0 bar ±5%); e�g� in the event of a
deviation of the mounting location of the sensor and the zero point level for
level measurement�
► Make sure that no pressure is applied to the system�
► Press [Mode/Enter] until [tCOF] is displayed�
► Press [Set] and keep the buton pressed�
> The current offset value (in %) briefly flashes, then the current system
pressure (in the selected display unit) is displayed�
► Release [Set]�
► Press [Mode/Enter] briefly to confirm the new offset value�
9.4.2 Setting the delay time for OUT1
[dS1] = switch-on delay / [dr1] = switch-off delay�
► Select [dS1] or [dr1] and set the value between 0�1 and 50�0 s (at 0�0 the
delay time is not active)�
9.4.3 Setting the output polarity for OUT1
► Select [P-n] and set [PnP] or [nPn]�
9.4.4 Setting the damping for the switching signal
► Select [dAP] and set value between 0�1 and 100�0 s (at 0�0 = [dAP] is
not active)�
dAP value = response time between pressure change and change of the
switching status in seconds�
[dAP] influences the switching frequency: f
max
= 1 ÷ 2dAP�
[dAP] also affects the display�
9.4.5 Setting the damping for the analogue signal
► Select [dAA] and set value between 0�1 and 100�0 s (at 0�0 = [dAA] is
not active)�
dAA value = response time between pressure change and change of the
analogue signal in seconds�
