Function bar
Free, non-assigned function button
Zoom readings
Hold current reading
Display max. values, since switch-on
Display min. values, since switch-on
Mean calculation
Activate volume flow meas. (with a velocity or external
differential pressure probe or internal pressure probe)
Activate/deactivate velocity measurement (with an external differential
pressure probe or the internal pressure probe)
Measurement range 40 hPa for internal pressure sensor
Measurement range 200 hPa for internal pressure sensor
Zero pressure probe at user-defined probe socket (at least one
differential pressure probe)
Zero the CO probe
Start/stop measurement program
Determine system configuration
Save readings
Print readings
Printer line feed
Turbulence calculation (with connected turbulence probe)
Starts the measuring gas pump and indicates the readings on the display. When
the function key P Start is clicked on, the function key changes to P Stop
The measuring gas pump stops, the readings are frozen at Hold
Switches on and zeros velocity rate measurement with Pitot tube and pressure probe
Manual storing of the current values under the displayed location names.
Use of the two temperature inputs of the analyser box as separate
2-channel temperature measurement with differential temperature display.
Activates the separate differential pressure measurement in the analyser box
(draught measurement).The pump is stopped automatically once "d P" is activated.
Initiates the purging and zeroing phase (1 minute). The device draws fresh air
through the measurement gas inlet or the fresh air valve (if fitted).
Manual change from measured gas to atmospheric air
Manual deactivation of an activated CO sensor
and purging with fresh air.
Manual activation of a deactivated CO sensor
in the gas path.
Switching the dilution stage (digit in front of x corresponds to the set
dilution factor)
Switching the HC module on/off
Direct display of all error messages
