4.2 Numeric keypad
It may happen that a numerical entry has to be made; for example, when entering the storage interval. To enter this function, each key changes its function to a specific numeric key. For each entry, all four cells must always be completed. A comma key is also available for volume flow measurement.

Switching the meter on and off

To switch the meter on and off, press and hold the on/off key for at least two seconds.
5.1 Automatic power off
If no entry is made within five minutes after switching on, the meter switches itself off. To deactivate this function, hold down the Enter key when switching on and switch on the meter. The display shows “no” The automatic power off function is now deactivated. Now release all keys to make a measurement. The automatic power off function always reactivates as soon as the meter is switched off.

Making a measurement

To make a measurement, align the flow sensor with the direction of the flow. An arrow on the head of the sensor indicates the orientation in relation to the wind flow. Wait for at least two seconds for the reading to stabilise.
6.1 Beaufort scale
The Beaufort scale is always active and shows the current wind force category

Wind force| Designation of the wind force| Designation of the sea state (wind sea)
---|---|---
0| Calm| Completely calm, smooth sea
1| Light air| Calm, rippled sea
2| Light breeze| Mildly agitated sea
3| Gentle breeze| Mildly agitated sea
4| Moderate breeze| Slightly agitated sea
5| Fresh breeze| Moderately agitated sea
6| Strong breeze| Rough sea
7| Near gale| Very rough sea
8| Gale| Moderately high seas
9| Strong gale| High seas
10| Storm| Very high seas
11| Violent storm| Heavy sea
12| Hurricane| Exceptionally heavy sea

6.2 Setting the flow unit
To set the unit of the flow velocity, press the “UNIT” key. You can choose between m/s, km/h, ft/min, knots and mps. The default setting is m/s.
6.3 Setting the temperature unit
To set the temperature unit displayed, press and release “°C/°F” once. You can choose between °C and °F. The default setting is °C.

Volume flow measurement

For a volume flow measurement, first press the “VEL/FLOW” key to select between velocity and volume flow measurement. This is signalled by “VEL” (speed measurement) and “FLOW” (volume flow measurement) on the display. Depending on the entered area and the measured wind flow, the measured value can also be significantly higher than it is possible to display. In this case, “x100” or “x10” is displayed next to the measured value. The measured value in the display must then be multiplied by 100 or 10 accordingly.
7.1 Setting the unit of the volume flow measurement
To select the unit FT³ or m³, press and release the “UNIT” key once.
Hint:
The function also has an effect on the area specification.

7.2 Area specification for volume flow measurement
In order to perform a volume flow measurement, it is mandatory to perform an area measurement of the flow. To do this, press the “AREA/SAMPLE” key in volume flow mode. Now enter the area.
The unit of measurement m2 flashes next to the display. Set the corresponding unit of measurement before entering the area.
7.3 2/3 MAX volume flow measurement
During the volume flow measurement, it is possible to display 2/3 of the maximum volume flow.
To do this, press the “ENTER” key. 2/3 MAX” appears on the display. Only 2/3 of the maximum measured value will be displayed. Press the “ENTER” key again to exit the mode.

Lowest, highest and average measured value

For velocity and volume flow measurement, the lowest / highest and the average measured value can be displayed by pressing a key. To use these functions, repeatedly press the “MAX/MIN” key until you have reached your desired function.
8.1 Highest measured value
When displaying the highest measured value, only the highest measured value is displayed after activating this function. When “MAX” is displayed, this function is active. When the function is changed, the value expires. 8.2 Average reading
When the average reading is displayed, the average of the last 10 seconds is displayed. With the “AVG” display, this function is active. If the function is changed, the value expires. 8.3 Lowest measured value
When the lowest measured value is displayed, only the lowest measured value will be displayed.
When “MIN” is displayed, this function is active. If the function is changed, the value expires. 8.4 Freeze measured value
To freeze and hold the currently displayed reading, press and release the “HOLD” key once. The reading is now held. HOLD” appears on the display. Press the “HOLD” key again to resume the measurement.
8.5 Recording the measured values
To record individual measured values, the storage interval must be set to “0000” seconds. The storage interval can only be set when the air velocity measuring function “VEL” is set. To do this, press the “SAMPLE” key and now set the storage interval accordingly. Then press the “REC” key whenever you want to save the current measured value. The memory location used is shown on the lower display and the “REC” display flashes once briefly above the display.
For continuous recording, set a desired storage interval with the “SAMPLE” key. You can select between 1 … 9999 seconds. Then press the “REC” key once. The lower display briefly shows the storage interval. REC” is shown above the display. This signals that the measured values are being recorded. To interrupt saving, keep the “REC” key pressed. If you press the “REC” key again, recording will be restarted.
Date and time are only saved when recording with the software. 8.5.1 Read out data memory
To read out the data memory on the meter, press and release the “READ” key once. “READ” is now shown above the display. All readings displayed are now those from the memory. Each time you press the “READ” key, the next memory value is displayed. Now press the “AREA/SAMPLE” key and type in the memory location you want to read out. To return to normal measuring mode, keep the “READ” key pressed until “READ” disappears from the display.

8.5.2 Delete data
The meter has a memory with 960 measuring points. As soon as the memory is full, “FULL” is shown on the display.
To delete the measurement data on the meter, press and hold the “DEL” key for at least two seconds until “CLA” and is displayed and “DEL” lights up. All saved data have now been deleted.
Hint:
Only the entire memory can be deleted.

Software

To install the software, first go to the page:
https://www.pce-instruments.com/english/download-win_4.htm
where you can download and install the latest software. Then connect the meter to the PC and open the software with administrator rights. As soon as the meter is connected to the PC, the automatic power off function is deactivated.

The exported data is saved in XLS format. This could look like this, for example: After you have selected “Real Time Measure”, a new window opens for live measurement on the PC. From here, the measurement data is transferred directly to the PC. To set the read interval, click on “Option” and then select “Read interval(sec). In the next window, you can set the interval in seconds. Below the window, you can see whether a meter is connected. In addition, the current window can be printed. A print preview can be started before printing. There is also a status bar for the current status of a file import.
