5 Switching the meter on and off

To switch the meter on or off, press and hold the key.

6 Measurement preparation

Before making a measurement, slide the probe guard down. Switch on the device. Point the

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.

7.3 Average measurement (different points)

To determine the average of different measuring points, press the right

function key in measuring mode.

Press the right function key again to select . To save the

displayed values, now press the left function key . The values

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.

At the same time, you can change selected parameters with the function

keys. To open a setting, press the enter-V/F key. Press the back key to go

back one level. Press the enter-V/F key to confirm your entry.

8.2 Flow rate setting

To specify the dimensions for the flow rate, go to the settings and select the

menu item "Area/Funnel". Here, you can specify four different dimensions

for square as well as round areas. In addition, a cylindrical area can be

specified. The last selected area is adopted in measuring mode.

8.3 Automatic power off

Via the automatic power off function, the meter can be set to switch itself

off after the set time. The following setting options are available here:

"NONE" (function deactivated), 2 minutes, 10 minutes, 1 hour.

8.4 View saved data

To view the saved data, go to the settings and select the item "History". All

saved measurement data can be viewed there. It is not possible to delete

or edit the data on the meter itself.

Note: If no data has been saved, this item cannot be opened.

8.4.1 Transfer data to the computer

To transfer the measurement data to a computer, the meter must first be switched off. Now

connect the meter to a computer which recognises it as a mass data storage device. The data

can now be found in CSV data format.

8.5 Display brightness

To adjust the display brightness, go to the settings and open the item

"Brightness". You can now use the function keys to adjust the brightness

of the display.

8.6 Date and time

To set the date and time, go to the settings and open the menu item

"Data/Time Setup". Here, the date and time can be set in the format

YYYY/MM/DD. You can also choose between English and German style

here. Use the function keys to change the parameters as desired. Use the

enter-V/F key to accept the value and jump to the next item at the same

time.

8.7 Calibration

To calibrate the flow rate, go to the "Calibration" item in the settings. Here,

the displayed measured value can be set using a factor ("Gain"). The

default value is 1.00.

The coefficient range is between 0.5 and 2.
