6. Commissioning, operation
6. With the [▼/MIN] or [▲/MAX] buttons, enter the altitude.
7. With the [STORE/QUIT] button, confirm the entry.
8. Press the [SET/MENU] button.

Return to main menu.
The setting is only possible, if an absolute pressure sensor is connected to
sensor connection 1.
When the “Sea Level” function is activated, the arrow for 'SL' is indicated below in the
display. Once the altitude of the fixed location above sea level has been entered, the
instrument displays the absolute pressure at sea level.
When two absolute pressure sensors are connected, the “Sea Level” function
for both pressure sensors corresponds to the setting of pressure sensor 1
(applies only to the 2-channel version).
6.4.3 Measurement types (rAtE)
The instrument supports three different measurement types for various purposes.
Two of these (P.dEt and FASt) operate with an increased measuring frequency 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 area
■
Measurement of slowly changing or static pressures, e.g. calibration, leak testing,
atmospheric pressure measurement, etc.
■
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.
Application area 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).
