2.3.2 rAtE-P.dEt: peak detection

Measuring rate > 1000 Hz, the value is displayed unfiltered.
Application with logger function: Measuring of pressure spikes or
fluctuating pressures with a resolution of < 1.5 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 > 1000 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 log-
ger 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 independ-
ent of the selected measuring rate (slow, fast, peak detect).
Until sufficient values to calculate an average value have been collect-
ed (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.
Operation of min/max-value memory in conjunction with the averaging
function:
If averaging is activated and 'slow' measuring rate is selected

(rAtE-Slo), the min-/max-memory value relates to the average
display value.
If averaging is activated and 'fast' measuring rate is selected

(rAtE-FASt or P.dEt), the min-/max-memory value relates to the
internal measured values (pressure spikes can be detected).
