Switching the meter on and off
To switch the meter on or off, press and hold the
key.
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.
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. 
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. 
| Setting | Meaning |
| Unit | Set the unit |

| Auto-off | Set the automatic power off |
| History | Read memory |
| Brightness | Show brightness of the display |
| Date / Time | Set date and time |
| Calibration | Calibrate flow |
8.1 Set unit
To set the unit for the flow and the temperature, go to the Settings menu and to the Unit menu item. Here, you can select between the temperature or the flow rate. Then you can change the unit.
| Function | Units |
| Flow rate | m/s, m³/h / ft/min, CFM |
| Temperature | °C, °F |
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. Herethe displayed measured value can be set using a factor (“Gain”). Thedefault value is 1.00.
The coefficient range is between 0.5 and 2.
