3. Function
The current flow is presented on the display two times seconds.
Swema Flow 126 can display real or standard flow by measuring air
temperature and barometric pressure.
On/Off (RED button)
Turn on and off the instrument by pressing the RED button. When
turning on the instrument, the display will first show firmware ver-
sion and then battery voltage. ”It will after that go into BP (Back
Pressure) mode. When ”Real” is displayed SwemaFlow 126 the flow
at actual temperature och barometric pressure. To change to stan-
dard flow ”std” (The flow is recalculated to a density at 20°C and
1013hPa) the PC-program SwemaTerminal 3 is used. The program
can be downloaded at www.arwmisure.it
Toggle the display light by pressing the RED button while the BLUE
button is held down. The istrument is shot off automatically after
ten minutes if no button is pressed.
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 Back Pressure mode, Flow Factor mode and stored
values (notE).

Flow hood selection
For exhaust flow any hood size can be selected. For supply flow, use
a longer hood (650x650 or 250x650mm) to stabilize the flow.
The included 300x300 hood can be used for supply if it gives the
same result on the valve type as one of the longer hoods.
All hoods to SwemaFlow 126 can be used for exhaust flow measure-
ments.
BP Mode (Back Pressure)
When measuring with any Flow capture the flow may be influenced
by the Flow capture itself. The flow may be throttled. This can be
corrected by using Back Pressure mode. By measuring two times,
with and without an extra throttle ring, SwemaFlow 126 calculates
the flow that reflects the true flow with no capture interference.
It doesn’t matter if you start to measure with or without the throttle
ring the important thing is that one measurement is with the throttle
ring and the other one without. It’s important where the throttle ring
is placed, when measuring with the throttle ring it should always be
placed after the hot wires in the sense of flow direction.

BP Measurement (BLACK button)
Place the hood with the sealing list making a proper seal around the valve.
Start with or without the throttle ring and press the BLACK button
(button on the side).
SwemaFlow 126 will wait 2 seconds to let the
flow stabalize in the flow capture, the display will show ”P1” (Point 1)
and start to count up from 0 to 2 (the stabilization time). It will af-
ter that make a measurement for 5 second during wich the display
will show the measured value. When finished ”P2” (Point 2) will be
shown in the display. Within 1 minute Point 2 need to be measured
otherwise SwemaFlow 126 will return to Point 1. Remove or put on
the throttle ring and press the BLACK button again, SwemaFlow 126
will repeat the same procedure as for P1. When finished the display
will show the True value without any influence by the flow capture.
If the value is flashing it means that something is wrong and the va-
lue might not be correct, if so, make a new measurement. By pres-
sing the GREY button the lowest measurement (with throttle ring) of
the two points are displayed for 2sec before it return to the true va-
lue again. By pressing the BLUE button the higher of the two points
will be displayed for 2sec.
Save measurement (BLACK button held down)
When P1 and P2 is measured the measurement can be saved by
holding down the BLACK button for 2 sec. The display will show
which note number the measurment is saved as and then return to
measuring mode.
If you don’t want to save the measurement just press the BLACK
button and you will return to measurement mode without saving.

Take a measurement with a Flow Factor
To measure with the flow factor displayed next to F press BLACK
BUTTON for less than 2 seconds. To change the flow factor instead
hold down the BLACK button for minimum 2 seconds when F1.00
is shown. The first digit will start flashing. Change value by pres-
sing GREY or BLUE button. When correct value is choosen confirm
by press shortly the BLACK button and the second digit will start
flashing. Reapet the same procedure with the second and third digit.
After the third digit is confirmed the instrument will start measuring
in F-mode. Measuring can be stored in the same way as in BP-mode.
To return to BP Mode press GREY button 3 times (First press will
show FX.XX, second will show notE and the third will take you to BP
mode).
HOLD function (BLACK button)
If the BLACK button is pressed down shortly the display will freeze
the measured value. ”Hold” is shown in the upper left corner of the
display. Press the BLUE button to toggle between the freezed values
(freezed air flow, temperature and barometric pressure).
Realese frozen values by pressing down the BLACK button for less
than 2 seconds.
Save measurement (BLACK button held down)
If a measurement is freezed it can be saved by holding down the
BLACK button for 2 sec. The display will show which note number
the measurment is saved as in the note book and then return to
measuring mode.
Flow Factor Measurement (F-mode)
In Flow Factor mode the flow is multiplied with a flow factor (flow
factor 1.00 will not alter the flow). A flow 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 certificate. The dis-
paly will show the text ”Factor” when the instrument is in F-mode.
While in BP Mode change to F-mode by pressing the GREY button.
(Bp-mode does not use a Flow factor) The instrument will change to
F-mode and display F1.00 or the value of flow factor that the instru-
ment used last time in F-mode after being turned on. For example
F1.10 will multiply measured flow with 1.10 and display the result.

Note book (notE)
If GREY button is pressed two times when in BP Mode notE will be
displayed. To enter the note book press the BLACK 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 BLACK button. With
GREY and BLUE button it’s possible to scroll through the saved mea-
surements in the note (air flow, temperature and barometric pres-
sure). To return to notes press the RED button. To erase the note
memory hold down the BLACK button for 2sec, ”E ALL” (Erase All?)
will be shown in the display. To erase the note memory hold down
the BLACK button for 2sec, ”E ALL” (Erase All?) will be shown in
the display. After all notes are erased ”notE” will be shown in the
display, press GREY button to go to BP Mode. Use the PC-program
SwemaTerminal 3 to transfer saved data to PC.

4. Charging
SwemaFlow 125D has built-in rechargeable Li-ion-batteries. Battery
charge time is approxematley 4h. The charger can be connected to
the instrument longer without damaging the battery. The battery
can also be charged with a USB cable connected to a computer. The
green led will have a fixed light during charging, when fully charged
the green led will be turned off. It is recommended not to use the
instrument while charging. Therefor the display is blinking as a war-
ning during charging. Caution! Use only the original charger other
charger can damage the batteries.
Batterinivå
När du slår på instrumentet kommer displayen att visa spänningsni-
vån på batteriet. Ett fulladdat batteri visar ungefär 4,1 V (den kom-
mer att sjunka till 3,8-3.9V ganska snabbt). När spänningen är lägre
än 3,1 V kommer en batteri symbol att börja visas på displayen. När
spänningen är lägre än 2,8 V kommer instrumentet att automatiskt
5. Driver installation
To use SwemaFlow 126 with a Windows 10 PC, just connect the USB
cable and wait for the driver installation to complete. To use Swema-
Flow 125D with an earlier OS driver matching .inf-files must be used
by the OS. The necessary files and drivers are automatically installed
with the free software ”SwemaTerminal 3”.
1. Download ”SwemaTerminal 3”
2. Unzip the file and run the setup file. 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/
