Push “P/V/F” three times to switch to the volume ow mode (FLOW). Push the button “Unit ” several times if required and then
select the desired measuring unit.
The anemometer display shows the saved form of the ow channel (rectangular or round) with the associated dimensions.
If you use any other ow channel for the current measurements than the one that has been saved, you have to re-dene the
channel data in the setup.
Push the “setup” button for more than 3 seconds and make the new settings as described in chapter
.
The functions “Hold”, “Save”, “MIN/MAX/AVG”, “Zero” and “Setup” cannot be used while measuring pressure, ow speed or
volume ow.
The current environmental temperature is displayed in the second display (20). The button “Unit ” switches between the measur-
ing units °C and °F.
Push “HOLD/ZERO” once to “freeze” the value currently displayed.
To deactivate the “HOLD” function again, push “HOLD/ZERO” again.
Push the button “MAX/MIN”, to browse through the min, max and average values. Additionally, either the elapsed time since calling
of the “MAX/MIN/AVG” function or the time at which a maximum or minimum value was measured is displayed.
Push the “P/V/F” to display the maximum, minimum and average values for pressure, ow velocity and volume ows.
Push the button “MAX/MIN” for 2 seconds to leave the “MAX/MIN”AVG” mode again.
Use the anemometer to save the measuring data for pressure, ow velocity and volume ows separately in up to 99 data records
each.
To save a data record push the button “SAVE/CLEAR” during the measuring process.
If all 99 memory slots are assigned, you cannot deposit any further data records. Instead, the display shows the message “FU”
(FULL: memory full) when you push the “SAVE/CLEAR” button. To clear memory for new measured data, proceed as described
below in chapter 18 .
