6. Commissioning, operation
When two absolute pressure sensors are connected, the “Sea Level” function
for both pressure sensors corresponds to the setting of pressure sensor 1.
6.4.3 Measurement types (
rAtE
)
The instrument supports three different measurement types for various purposes. Two of
these operate with an increased measuring rate of > 1,000 measurements/s.
6.4.3.1 Standard measurement (
rAtE
-
SLo
)
The measuring rate is 4 Hz. The averaging and filter functions are active.
Application range
■
Measurement of slowly changing or static pressures, e.g. calibration, leak testing,
atmospheric pressure measurement,
■
Highest measurement accuracy, insensitive to disturbances, low current consumption.
6.4.3.2 Peak value detection (
rAtE
-
P
.
dEt
)
The measuring rate is > 1,000 Hz and the measuring signal is displayed unfiltered.
Field of application in combination with logger function
■
Measurement of pressure spikes or fluctuating pressures with a resolution of < 1 ms.
■
The cyclic logger function records the arithmetic mean value, the highest and the
lowest pressure during the chosen time interval.
In this setting, there is an increased current consumption and the
measurement is susceptible to interference (also electromagnetic
interference).
6.4.3.3 Fast measurement = Fast (
rAtE
-
FASt
)
The measuring rate is > 1,000 Hz and the measuring signal is displayed filtered. As a
result, it is less sensitive to interference and the short-term spikes are filtered out. Other
than that, this function is identical to
