Allocation options of function buttons

Hold
freezes the last current reading on the display.
MAXMIN
shows the largest/smallest display value since
switching on. If there is more than one value, all of
the display values are stored separately and
analysed.
Mean
for calculating mean value. This function is available
for all parameters.
Continue
extends the mean calculation by an additional set
measurement duration within the same log.
New
measures a new mean in a new log.
End
interrupts calculation of the mean value.
Vol
extends the display with the "m
flow) when a velocity probe is connected. The
diameter of the channel, two side lengths or the area
can be given as the parameters. The duct dimensions
are individually saved and processed for every
measurement location.
Standard volume flow
hPa=0
carries out a zero-point calibration when the pressure
probe is connected.
m/s
"m/s" extends the display by the velocity value
calculated from pressure when a differential pressure
probe is connected.
hPa
"hPa" deactivates this channel.
Turb.
calculates degree of turbulence when a comfort level
probe (0628.0009) is connected.
The function button is deactivated.
CO=0
repeats the zero-point calibration if a CO probe is
connected.
