5 Switching the meter on and off
To switch the meter on or off, press and hold the key.
6 Measurement preparation

opening of the sensor in the direction of the flow to be measured. When you have finished your
measurement, push the guard back up so that the sensor system is not damaged.
7 Measuring mode
7.1 Main display
After the meter has been switched on, the velocity measurement is carried
out immediately. At the same time, the current temperature is measured
and displayed. To select between the velocity and the flow rate
measurement, press and release the enter-V/F key once. The "V" on the
display stands for velocity and the "F" for flow. The flow rate depends on
the velocity and the set area. You can set the area under 8.2 Flow rate
setting to set the area.
Note: Saving individual measured values is not possible in normal
measuring mode:
7.2 Average measurement (time-dependent)
To display the average, press the right function key in measuring mode to
select . The display now shows for the average
reading (time-dependent) and . Now press the left function key to
select . The current velocity, the average, the highest and the
lowest measured value are displayed here. Press the left function key to
save the displayed values . Press the right function key to start or
pause the current average measurement . To repeat the average
measurement, go to normal measurement mode with the back key and
start the average measurement again.

are saved once per keystroke. To include the current measuring point in
the average measurement and select the next one, press the right function
key . To repeat the average measurement, go back to normal
measuring mode with the back key and start the average measurement
again.
8 Settings
To make settings, press the left function key in measuring mode.
Use the function keys to select between the individual functions displayed.
