Push “P/V/F” three times to switch to the volume flow 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 flow channel (rectangular or round) with the associated dimensions.
If you use any other flow channel for the current measurements than the one that has been saved, you have to re-define the
channel data in the setup.
Push the “setup” button for more than 3 seconds and make the new settings as described in chapter “Setting the flow channel
parameters” .
The functions “Hold”, “Save”, “MIN/MAX/AVG”, “Zero” and “Setup” cannot be used while measuring pressure, flow speed or
volume flow.
13. dISPLay temPerature
The current environmental temperature is displayed in the second display (20). The button “Unit ” switches between the measur-

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, flow velocity and volume flows.
Push the button “MAX/MIN” for 2 seconds to leave the “MAX/MIN”AVG” mode again.
16. SaVe meaSurIng data
Use the anemometer to save the measuring data for pressure, flow velocity and volume flows 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 “delete saved measuring data” .
