xxxx

Higher pressure limit

4.1.5 .MPM measurements per minute

.MPM.xxx

xxx

Number of measurements per minute (6 ... 4200)

The command sets the number of measurements performed in one minute. As default, the
MPM is 60.

60 min

-1

= 1 s

-1

= 1 measurement per second

4.1.6 .AVRG defining averaging

.AVRG.xxx

xxx

Number of measurements of which the average
is calculated (0 ... 255). The default

AVRG

is 0.

The command sets the number of measurement points that are used for the calculating an
average pressure reading. This is not a moving average.

Example

If the number of measurements per minute is set to 30 and the averaging to 5, the pressure

reading is updated every 10 seconds.

4.2 Operating commands

To activate a new setting, reset the barometer with the command

.reset

.

4.2.1 .P outputting single message

.P

The command outputs the latest multi-point corrected pressure reading with 2 decimals.

.P<cr> (command invisible)
