9.4.3 Set delay for the switching outputs
[dS1] / [dS2] = switch-on delay for OUT1 / OUT2�
[dr1] / [dr2] = switch-off delay for OUT1 / OUT2�
► Select [dS1], [dS2], [dr1] or [dr2] and set a value between 0�1 and 50 s
(at 0�0 the delay time is not active)�
9.4.4 Set switching logic for the switching outputs
► Select [P-n] and set [PnP] or [nPn]�
9.4.5 Set damping for the switching signal
► Select [dAP] and set a value between 0�00 and 30�00 s; (at 0�00 [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 has an effect on the display�
9.4.6 Set damping for the analogue signal
► Select [dAA] and set a value between 0�01 and 99�99 s; (at 0�00 [dAA]
is not active)�
dAA value = response time between pressure change and change of the
analogue signal in seconds�
9.4.7 Calibrate curve of measured values
► Set a defined reference pressure between ASP and AEP in the system�
► Select [CAL]�
► Press [Set] briefly�
> [CP1] is displayed�
► Press [Set] for 5 s�
> The pressure measured by the unit is displayed�
► Press [Set] until the set reference pressure is indicated (measured
pressure = reference pressure) or the corresponding analogue signal is
provided on OUT2�
Maximum correction value = ± 2 % of the final value of the measuring
range�
► Press [Mode/Enter] briefly�
> [CP1] is displayed�
► Press [Mode/Enter] briefly�
> [CP2] is displayed�
