The spacers enable the user to realize different measuring gaps.
The assembling is done via a threaded hole on the static part at the under
surface of the measuring device.
The base device can measure at a gap width of 140 mm. When attaching the
first and the second spacer, the device is capable of measuring gap width of
210 mm. Using spacers 1, 2 and 3 gives a gap width of 310 mm. By attaching
the spacers 1, 2 and 4 a gap width of 410 mm is the result. Using all of the four
spacers, a gap width of 510 mm can be realized (refer chapter 1.4.1 “Spacers”).

4.4 Measuring
The measuring device has to be turned on and connected via Bluetooth or USB
to perform a measurement.
4.4.1 Device positioning
The instrument is to be used such that the static part is connected to the stop
of the closing system and the movable part faces towards the moving edge. In
case of two moving edges, choose one of the edges for the static part and
follow the movement of this edge manually. The force initiation area and the
moving edge should be in parallel to each other.
Figure 10: Parallel device positioning
Lined force Initiation:
The force should be initiated on a line in an angle of 90 ° to the symmetrical
axis of the device. The unit under test should hit the centre of the initiation disc.

Axis of symmetry
Force initiation
Closing systems with one moveable door:
Place one of the force initiation areas on the static part of the door without
giving pressure to the sensor. The opposite force initiation area is facing the
moveable part of the closing system.
Closing systems with two moveable doors:
We recommend 2 methods to measure closing systems with two moveable
parts:
a) Method 1: Place the device at the position between the two moveable
parts where they will meet in fully closed position.
b) Method 2: Place the static part of the device on one of the two
moveable doors without giving pressure to the sensor. Guide the
device along the distance of the moving door until the force initiation
area hits the opposite door. Hint: If the sensor is exposed to pressure
during guidance and the trigger value is reached then the device will
start measuring.
4.4.2 Mounting spacers
There is the possibility to mount spacers to the measuring device to adapt to
several different door apertures which are required to measure according to

Pinch Force Meter FM300BT
Version 1.5 Seite 19/23
specific norms. This point is related to the applied norm and is therefore
optional (refer chapter 1.4.1 “Spacers” and chapter 3.2 “Assembly of Spacers”).
4.4.3 Start measuring
The measurement is started by a short button press. Alternatively, it can be
started through the software (either PC or Android device). During the
measurement the LED shows a yellow light and the measured values are
displayed in the software.
Figure 12: Device during measurement
Permanently yellow
➔Device is measuring
The device will perform a taring action after initiating the measurement. This
will take about 0.5 seconds. If there is a force applied to the measuring device
during this period, then the following values will be decreased by this value.
The measurement will be stopped automatically if the measuring values will be
below the defined force value for a certain time period. If the measurement
should be stopped earlier then it can be done manually by pushing the stop
button either on the measuring device or in the software.
The LED will show a permanently blue light after stopping the measurement.
4.5 Turning Off
Pushing the button on the measuring device for a time period longer than 3
seconds will turn the device off. Alternatively, the device can be turned off by
the Android App (see chapter Fehler! Verweisquelle konnte nicht gefunden
werden. “Fehler! Verweisquelle konnte nicht gefunden werden. App”).
