User Settings (Optional); Carry Out Zero Point Calibration; Set Delay Time For Out1; Set Switching Logic For Out1 - ProMinent DULCOMETER PH-501 Assembly And Operating Instructions Manual

As an alternative:
Select [ASP] and set the measured value at which 4 mA is provided
(20 mA at [OU2] = [InEG]).
Select [AEP] and set the measured value at which 20 mA is provided
(4 mA at [OU2] = [InEG]).
Minimum distance between ASP and AEP = 25 % of the final value of the
measuring range (turn-down 1:4).

9.4 User settings (optional)

9.4.1 Carry out 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
value.
As an alternative: automatic adjustment of the offset in the range 0 bar ±
5 %.
Make sure that no pressure is applied to the system.
Touch [Mode/Enter] until [tCOF] appears.
Touch [Set] and keep it touched.
> The current offset value (in %) flashes briefly.
> The current system pressure is displayed.
Release [Set].
Touch [Mode/Enter] briefly (= to confirm the new offset value).

9.4.2 Set delay time for OUT1

[dS1] = switch-on delay / [dr1] = switch-off delay.
Select [dS1] or [dr1] and set a value between 0.1 and 50 s (at 0.0 the
delay time is not active).

9.4.3 Set switching logic for OUT1

Select [P-n] and set [PnP] or [nPn].

9.4.4 Set damping for the switching signal

Select [dAP] and set a value between 0.01 and 30 s.
dAP value = response time between pressure change and change of the
switching status in seconds.
[dAP] influences the switching frequency: f
[dAP] also has an effect on the display.
20
= 1 ÷ 2dAP.
