Configuration
To change device settings, press key: ´set/Menu´ for 2 seconds. This will call the configuration
menu (main display: “Set”).
Pressing key: ´set/Menu´ changes between the menues, pressing key: ´Tara´
jumps to the
referring parameters, which can be selected with key: key: ´Tara´.
The parameters can be changed with key: ´Min´ or ´Max´. Pressing key: ´set/Menu´ again jumps
back to the main configuration menu and saves the settings.
Key: Quit finishes the configuration and returns to standard measuring operation.
5.1
(Unit) Different kinds of pressure units
Depending on the pressure range the pressure value can be displayed in or of the following units:
mbar, bar, Pa, kPa, MPa, mmHg or PSI.
5.2
(SL) Sea level correction for absolute pressure sensors
Is an absolute pressure sensor to the instrument connected, then the device displays the absolute
pressure measured of the sensor. This is not necessarily the same like the values given by
weather stations! The weather stations‘ values are giving the pressure at sea level. Usually the
sensor is placed above sea level and therefore, if the value at sea level (zero) is to be measured,
the pressure loss resulting from the actual level above sea level has to be considered! To correct
the measuring display activate the „Sea-Level-Function“ (SL). Then enter the altitude above sea
level of the sensors´ location in meters (Alti). When activated, the display shows the SL-arrow and
the device displays the pressure value at sea level.
5.3
(rAtE) Different kinds of measuring: „ rAtE-Slo, -P.dEt, -FASt“
Three different kinds of measuring pressure are supported. Two of them are working with high
measuring frequency of more than 100 measurings per second. If one of them was chosen in the
configuration (see above), this will be displayed in the secondary display: „P.dEt“ or „FASt“.
5.4
rAtE-Slo= Standard measuring
Measuring rate 4Hz, averaging and filter functions are active.
Application: Measuring of slowly changing or static pressures, e.g. measuring of leakproofness,
atmospheric pressure...
Highest accuracy, high noise immunity (EMI and unstable measuring signals), low power
consumption.
