Start-up and configuration
Checking the measuring range (differential pressure span)
1. Press key (in start screen) to go to the main menu.
2.
Select [Start-up| 1] with
or key and confirm with key.
3. Select [Differential pressure span| 1.7] with or key and confirm with key.
The current values for differential pressure, span and maximum differential pressure
(Δp
100
) are displayed.
4. Use a precision regulator to apply a test pressure corresponding to the max. differential
pressure Δp
100
while monitoring the pressure gauge.
Î
Set points: Δp = 0 mbar or 4 mA (read note on ‘Gas column correction’.)
Î
When the reading and output signal do not match the indicated Δ p
100
value, readjust
the upper range value (span).
Adjusting the measuring range (span)
1. Press key (in start screen) to go to the main menu.
2.
Select [Start-up| 1] with or key and confirm with key.
3. Select [Differential pressure span| 1.7] with or key and confirm with key.
4. Press key to set the span.
The span setting is active. If it is to be no longer used, it must be reset ([Differential pres -
sure span| 1.7] parameter).
7.5 Calibrating the pressure sensor
To be able to calibrate the pressure sensor, make sure that the pressure sensor in the differen-
tial pressure meter is activated ([Pressure sensor| 2.1.4] parameter = YES).
How to proceed:
1. Press key (in start screen) to go to the main menu.
2.
Select [Device settings | 2] with or key and confirm with key.
3. Confirm [General | 2.1] with key.
4. Select [Pressure sensor | 2.1.4] with or key and check whether the parameter is
set to YES. If this is not the case:
Set the [Pressure sensor | 2.1.4] to YES with key.
