(see above), this will be displayed in the lower display: "P.dEt" or
"FASt".

2.3.1 rAtE-Slo: standard measuring

Measuring rate 4 Hz, averaging and filter functions are active.
Application: Measurement of slowly changing or static pressures,
e.g. leak testing, atmospheric pressure...
Highest accuracy, high noise immunity (EMI and unstable
measuring signals), low power consumption.

2.3.2 rAtE-P.dEt: peak detection

Measuring rate > 100 Hz, the value is displayed unfiltered.
Application with logger function: Measuring of pressure spikes or
fluctuating pressures with a resolution of < 10 ms. The cyclic
logger function records the arithmetic mean value, the highest and
the lowest peak during the chosen time interval.
Higher power consumption, measuring is sensitive to noise
(EMI,..).

2.3.3 rAtE-FASt: fast filtered measuring

Measuring rate > 100 Hz, but the value is filtered slightly (higher
noise immunity than P.dEt, small peaks will be filtered out), apart
from that, identical behaviour to P.dEt.

2.4 Averaging function

The averaging function acts on the displayed values (LCD and
serial interface). It is completely independent of the averaging
within the logger function, please don't mix them up!
The averaging integrates the measured values during a chosen
time interval and then calculates the average display value. It is
independent of the selected measuring rate (slow, fast, peak
detect).
Until sufficient values to calculate an average value have been
collected (dependant on selected averaging time), the upper
display shows "----", the lower display shows a ´countdown´.
During an active low-power-logging procedure the average is
always deactivated.
