2. Technical data
1.

3. Function
SwemaFlow 4000 calculates the average value of the airow during
2 seconds. The average ow is presented on the display with an up-
date two times per second. SwemaFlow 4000 compensate automa-
tically for the air density by measuring air temperature and barome-
tric pressure.
On/Off (RED button)
Turn on the instrument by pressing the RED button. When turning
on the display will go trough a sequency of showing the rmware
version, the battery status and showing the barometric pressure, it
will after that go into measuring mode. Turn off the instrument by
pressing the RED button.
The display light is turned on by pressing down the blue button
when turning the instrument on. The light is shut off by turning off
the instrument.
Unit (BLUE button)
By pressing the BLUE button the display toggles between l/s, m3/h,
air temperature (°C) and barometric pressure (hPa). When set to US
units it toggles between cfm, air temperature (°F) and barometric
pressure (inHg).
Mode (GREY button)
Toggle between Standard mode, Flow Factor mode and stored values
(notE) with Grey button.
2.
Standard Measurement
Place the hood with the sealing list making a proper seal around the
valve. Read the air ow value from the display.

HOLD function (RED button on handle)
If the button on the handle (small red button) is pressed down
shortly the display will freeze the measured value. This will be
shown with the text ”Hold” is shown in the upper left corner of the
display. Realese it by pressing down the button shortly again. Press
the BLUE button to toggle between the freezed values (freezed air
ow, temperature and barometric pressure).
Save measurement (RED button on handle holded down)
If a measurement is freezed it can be stored by holding down the
button on the handle (small red button) for 2 sec. The display will
show which note number the measurment is saved as and then re-
turn to measuring mode.
FF Measurement (Flow Factor)
In Flow Factor mode the ow is multiplied with a ow factor (ow
factor 1.00 will not alter the ow). A ow factor can be used to com-
pensate for example a leakage. Warning: Changing to anything else
than 1.00 will alter the reading from calibration certicate.
If in Standard measuring mode and the GREY button is pressed the
display will show F1.00 (or the value of ow factor that the instru-
ment is set to).
Make a FF Measurement (RED button on handle)
To measure with the ow factor displayed (example F1.10 will mul-
tiply measured ow with 1.10 and display the result) press button
on the handle (small red button), the text ”Factor” on the display is
shown to indicate that you are in FF-mode. To change FF-value hold
down the button on the handle (small red button) for minimum 2
sec when F1.00 is shown. The rst digit will start ashing, change
value by pressing GREY or BLUE button. When correct value is
choosen conrm by press shortly the button on the handle and the
second digit will start ashing, repeat the same procedure with the
second and third digit. After the third digit is conrmed the instru-
ment will go to FF mode. Measurement can be stored in the same
way as in regular measuring mode.
To return to regular measuring mode press GREY button 3 times
(rst press will show FX.XX, second will show notE and the third will
take you to Standard measurement mode).
3.

Note book (notE)
If GREY button is pressed two times when in standard measuring
mode notE will be displayed. To enter the note book press the but-
ton on the handle (small red button). ”Note” and the number of the
last saved note will be shown on the display. With GREY and BLUE
button it’s possible to scroll through the saved notes. To return to
notE press RED button.
To see saved measurement in a note press button on the handle
(small red button). With GREY and BLUE button it’s possible to scroll
through the saved measurements in the note (air ow, temperature
and barometric pressure). To return to notes press the RED button.
To erase the note book memory hold down the button on the handle
(small red button) for 2sec, ”E ALL” (Erase All?) will be shown in the
display. To return to notes press the RED button, to erase all notes
hold down the measuring button (small red button on handle). After
all notes are erased ”notE” will be shown in the display, press GREY
button to go to regular measuring mode.

4. Charging
SwemaFlow 4000 has built-in rechargeable Li-ion-batteries. Battery
charge time is approxematley 4h (80% after approx. 2h). The char-
ger can be connected to the instrument longer without damaging
the battery. The green led will have a xed light during charging,
when fully charged the green led will be turned off. You can use the
instrument while charging. Caution! Use only the original charger
other charger can damage the batteries.
Battery check
When turning on the instrument the display shows the voltage of
the battery. A fully charged instrument shows approximately 4.1 V
(it will drop to 3.8-3.9V quite fast). When the supply voltage is lo-
wer than 3.2 V a battery symbol will be visible on the display. When
the supply voltage is lower than 2.9 V the instrument will be auto-
matically shut off.
5. Driver installation
To be able to use SwemaFlow 4000 with a PC or to change settings a
driver for the probe needs to be installed. The drivers are automatically
installed after installation of the of the fre software ”SwemaTerminal
3”.
1. Download ”SwemaTerminal 3” (is a zip-le) from www.swema.
com.
2. Unzip the le and run the setup le. When the setup is done con-
nect the USB cable to the PC and turn the instrument on. The PC will
now install the necessary drivers automatically.
In case the driver installation dosen`t succeed you can also do it ma-
nually. Open the device manager, right click on ”unknown device” and
then ”update driver”. The drivers can be found at ”C:/Program Files/
Swema” (make sure that the box ”include sub folders” is checked).

6. SwemaTerminal 3
With SwemaTerminal 3 it’s possible change settings, print stored
measurements, update rmware, print calibration protocol, do on-
line logging and store the logged data on your PC. Information of
what kind of instrument and at which COM-port it’s connected can
be found on the top left side.
”Flow”, ”Temperature” & ”Pressure”:
SwemaTerminal 3 shows the air ow, temperature and barometric
pressure that SwemaFlow 4000 is currently measuring.
”Averaging time”:
Averaging time is used to decide how fast the displayed values will
be updated. A higher ”Averaging time” will use more internal samp-
les for the averaging and by that give a more stable value.

7.
”Actual” or ”Standard ow”:
If set to ”Actual” the ow shows as it is at present temperature and
barometric pressure. If set to ”Standard” the ow is presented as it
is at standard conditions (1013hPa & 20°C).
”Point” or ”Comma”:
Set point or comma as decimal separator for the the prinout of sto-
red values and for logged measurment to PC.
”US” or ”EU/ASIA”:
Set unit system to US (ft3/min, °F, inHg) or EU/ASIA (l/s, °C, hPa).
”Auto Shutoff”:
Set in minutes after how long time the instrument will be turned off
if not used. If set to 0 min the auto shutoff is disabled.
Log:
Press the ”Log” button to start an online logging of measured values
(will be saved as a txt-le). If the box to the left of ”Unit” is checked
the logged values will be shown/stored with chosen unit (m/s, fpm
etc.) With ”Freq:” it’s possible to set how often a new value should
be stored.
”Read calibration certicate” and ”Read Notebook”:
By clicking on ”File” a dropdown menu is opened. It’s here possible
to show SwemaFlow 4000:s calibration certicate and print the sto-
red measurements to the PC.
