2. INTENDED USE

The pitot tube anemometer is designed for precise differential pressure measurement. Furthermore, the pitot tube anemometer records flow velocities of air and gases and ambience temperatures. In combination with a pitot tube, it is also possible to measure high air velocities.

The flow supply of the pitot tube anemometer is performed via a 9-Volt block battery (E-Block).

Operation of the pitot tube anemometer is possible both indoors and outdoors, but not in potentially explosive environments. The device should not be exposed to extreme temperatures, direct solar irradiation, high moisture or wetness. The pitot tube anemometer is not suitable for aggressive environments.

Read these operating instructions thoroughly and carefully, they contain a lot of important information for commissioning and operation. Always observe the safety information!

Any use other than that described above damages the product. Moreover, this is linked to dangers such as short circuit, fire, electric shock, etc. No part of the product must be modified or converted!

10. MEASURE PRESSURE

The main display (3) on the display shows the manometer pressure or the differential pressure up to 5,000 Pa. You can choose between the five measuring units psi, mbar, Pa, inH _2 O and mmH _2 O for the display.

Push "P/V/F" once to switch to the pressure mode (PRESS). Push the button "Unit▼" several times if required to select the desired measuring unit.

Connect a hose to the "+" input of the pitot tube anemometer and leave the "-" input open.

The device registers the ambience conditions via the hose opening. Push and hold the button "Hold/Zero" for 2 seconds to perform a zero reconciliation.

Place the open end of the hose in another environment than the anemometer.

The anemometer now shows the pressure difference between the ^+ input (ambience conditions at the hose end) and the - input (reference ambience conditions at the anemometer).

11. MEASURE FLOW SPEED

The anemometer measures flow velocities and volume flows based on the following standard conditions: 21.1^ ambience temperature, 1,013 mbar barometric pressure. The device has no automatic temperature compensation.

The main indication (3) of the display shows the flow velocity. It can be presented in five different measuring units: m/s, ft/min, km/h, mph, knots.

Push "P/V/F" twice to switch to the flow mode (VEL). Push the button "Unit▼" several times if required to select the desired measuring unit.

Connect the two hoses with the anemometer and the pitot tube as shown in the figure. The "+" input of the pitot tube anemometer is connected to the overall total pressure connection of the pitot tube by the white hose. Connect the "-" input of the measuring device to the connection for the static pressure at the pitot tube via the black hose.

Push and hold the button "Hold/Zero" for 2 seconds to perform a zero reconciliation.

For the most precise measurement possible, hold the opening of the pitot tube as precisely against the flow direction as possible - the deviation from the flow direction should not be larger than ± 10^

If the output measured value is negative or if you receive an error message ("Error"), check if the two hoses are correctly connected to the anemometer and to the pitot tube.

12. MEASURE VOLUME FLOW

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 measuring units ^ C and ^ F .

14. "HOLD" FUNCTION ("FREEZE" DATA ON THE DISPLAY)

Push "HOLD/ZERO" once to "freeze" the value currently displayed. To deactivate the "HOLD" function again, push "HOLD/ZERO" again

15. CALL MIN, MAX AND AVERAGE VALUES

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, 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".

17. CALL SAVED MEASURED DATA

To call saved data records in the corresponding operating mode (P = pressure, V = flow speed, F = volume flow), push the button "P/V/F".

Push and hold the "Avg/Rec" button for 2 seconds to display saved data records. The last data record saved appears in the display first.

Push the buttons "Unit" or "Unit" to browse the saved data records.

Push "Avg/Rec" to have the average value of all saved measured values displayed in the selected operating mode.

To leave the saving mode again, keep "Avg/Rec" pushed for 2 seconds again.

18. DELETE STORED MEASURED VALUES

To delete individual saved data records in the corresponding operating mode (P = pressure, V = flow speed, F = volume flow), push the button "P/V/F".

Push and hold the "Avg/Rec" button for 2 seconds to display saved data records. The last data record saved appears on the display first.

Push the buttons "Unit ▲" or "Unit ▼ to browse the saved data and select the desired data record.

Push "SAVE/CLEAR" to delete the selected data record. This reduces the displayed number of saved data records at the bottom right of the display.

To leave the saving mode again, keep "Avg/Rec" pushed again for 2 seconds.

To delete all data records, proceed as described in chapter 9 "Change Setup Setting" item 9.9 "Delete Memory".

19. MAINTENANCE AND CLEANING

If the battery status symbol in the display shows a low battery status, you need to replace the battery of the pitot tube anemometer by a new 9 V E-block. Proceed as described in chapter 21 "Replacing batteries". Other than that, the pitot tube anemometer is maintenance-free to you. Never take it apart. To clean the product, a dry, soft and clean cloth is sufficient. Clean the display very carefully to avoid scratches. Do not use aggressive detergents as these will cause discoloration of the casing.

20. ERROR MESSAGES

The measuring device has internal diagnosis functions. In case of malfunctions, the display outputs error messages and "freezes" all buttons.

Error code Cause
OL The pressure or flow velocity is above the measuring range.
-OL The pressure is below the measuring range
Error The flow velocity or volume flow is below the measuring range
FU The memory is full; no further data records with measuring data can be displayed

21. REPLACING BATTERIES

Switch off the anemometer.

Push the rear battery compartment lid of the housing down at the mark to open the battery compartment.

Replace the flat battery by a new 9 V E battery block (item no. 65 25 09).

Slide the battery compartment cover back onto the casing until it latches.

22. INSTALLATION AND USE OF THE PC SOFTWARE MANOMETER & FLOW METER

Insert the CD-ROM included with the pitot tube anemometer into the CD-ROM drive of your Windows PC.

Double-click the icon "Computer" on your desktop and then the icon of your CD-ROM drive to open the corresponding folder. You will find an installation file with the extension *.exe" there. Double-click the file name to start the installation process.
