5.4.3 Sea level correction for absolute pressure sensors

The CPH6300 measures the absolute pressure of the ambient air. This is not to be
confused with the "air pressure at sea level" given by the weather station! With this
pressure indication, the altitude-dependent atmospheric pressure drop is calculated.
The instrument is capable of making this air pressure altitude correction.
1. For this, activate the "Sea level function" (see chapter 5.3 "Configuration of the
instrument").
⇒
The setting is only possible, if an abs. pressure sensor is connected to sensor
connection 1.
2. Input the height above sea level in metres (see chapter 5.3 "Configuration of the
instrument").
⇒
With the sea level function active,
3. Once the height of the fixed location above sea level has been entered, the instrument
displays the absolute pressure at sea level.

5.4.4 Averaging

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 measurement).

This measurement is sensitive to noise (also against electromagnetic
disturbances) and the power consumption is increased.
Measuring rate > 1,000 Hz, but the value is filtered slightly (higher noise
immunity, small peaks will be filtered out), apart from that, identical

With 2 connected absolute pressure sensors, carry out the sea level function
for both sensors corresponding to the setting of sensor 1 (only applies to the
2-channel version).
The averaging function acts on the displayed values (display and serial
interface). It is completely independent of the averaging within the logger
