NOTE Remember to give the RESET command to initialize the new
measurement mode.
The measurement time (mtim) setting of 32 is recommended in order
to achieve the best output stability at the speed of 10 measurements
per second. The filter command ensures that no numerical filtering is
performed in the fast measurement mode. The MTIM and FILT
commands are used only together with the MMODE FAST command.
In the NORMAL measurement mode, the AVRG command replaces
the MTIM and FILT commands in the PTB220 series digital
barometers.
NOTE Always remember to return the switch SW4 to write DISABLE
position (OFF).
PULSE Selecting the PULSE output mode
PULSE a s r o
where:
a = ON or OFF (activation/deactivation)
s = SLOW or FAST (speed)
r = LOW or HIGH (resolution)
o = pressure offset (hPa/mbar units only)
The PULSE command is used to activate or deactivate the pulse ouput
mode and to set or inspect the desired parameters. SLOW/FAST
selection affects the pulse rate: SLOW speed equals to 5 kHz pulse
rate and FAST speed equals to 50 kHz pulse rate. LOW resolution
equals to 0.1 hPa/mbar pressure resolution and HIGH resolution
equals to 0.01 hPa/mbar pressure resolution. In order to minimize the
number of output pulses the user can define an offset pressure so that
pulse outputting starts from the selected pressure level.
