2. Introduction
The KMG-2000-G force-measuring device is used for the determination of dynamic and
static forces as well as the duration of these at the closing edges of doors and gates.
According to the standard, three single measurements must be made at each test point for
a normal measurement, the mean value of which then represents the measured value that
is relevant for standard purposes. The following four measured values are determined per
measuring operation in order to properly assess the closing force in accordance with the
standard:
1. Static force: Fs
2. Maximum dynamic force: Fd
3. Time in relation to dynamic force range td
4. End force on expiry of the measuring period Fe
of 5 seconds
Permitted Peak Forces in accordance with DIN EN 12453 (Extract)
The static force is the mean value of all the force values within the static time range.

The force graph must be measured three times for each test point. The mean value
is formed from the values obtained for Fd, Fs, Fe and td from each force graph.
These mean values must not exceed the limiting values set.
3. Measuring Device
The measuring device consists essentially of a measuring body complete with the test sur-
face, a centrepiece complete with electronics and a display, and the handgrip complete
with a battery compartment (Picture 1).

3.1. The KMG-2000 G force-measuring device is used for the routine, on-the-spot check-
ing of the closing forces on gates, e.g. following the installation of a new gate or for
the prescribed annual inspection of existing gates, with the result being recorded in
the inspection log book relating to each gate. It is possible to transfer the measured
values to a laptop or PC via the inbuilt USB interface which allows an accurate analy-
sis of the measured values to be carried out and any deviations from the set values
to be identified. The required software can be ordered as an extra.
3.2. It is stipulated in EN 12453 and DIN 16005 that each force-measuring device must be
sent to the manufacturer at least once a year for the purpose of calibration and ad-
justment. He will then test that it is compliant and approve the device for use for an-
other year.
3.3. The centrepiece of the KMG-2000-G contains an LCD display, on which all the
measured values, the force curves, the measured-value memory management func-
tion and user guidance are displayed.
•Measured-Value Display
All 4 measured values that are relevant for standard purposes are displayed simul-
taneously for each individual measurement and, following the third individual
measurement, the 4 mean values.
Individual Measured Values Mean Values
•Measured-Value Memory Management Function
All measured values of the individual measurements, up to 500 in number, and the
mean values calculated in each case from 3 individual values can be brought up on
the display along with their graphic representations.
•User Guidance
During the individual phases of the measurement process appropriate operating
advice is displayed, e.g.

4. Measurement of a Force Sequence
4.1 Carrying Out The Force Measurement
•Switch on (actuate any button as desired)
After switching on, the “start” display appears for
5 seconds:
During this time the language selection or the
options menu can be selected.
After 5 seconds the device is ready to carry out
force measurements.
The current status of the measured-value
memory is displayed top left, e.g.:
2. Normal measurement
3. Individual measurement
If the current normal measurement No.2 is to be cancelled, then by pressing button F2 it
is possible to switch ahead to normal measurement No.4. There will then be 3 indivi-dual
measurements available once more.
•Initialise measuring
A measuring operation is activated by pressing
button F3. The device is now ready to take meas-
urements. The measuring operation is started if a
force > 20 N is exerted on the test surface. The
force/time measuring operation then runs (for a
measuring period of 5 seconds).
•Carry out measuring operation
Hold the test area centrically (inner circle) to the
measuring points stipulated in the European draft
standards. The measuring points are specifically
prescribed in relation to the relevant type of gate
construction. (see Appendix).
Once the trigger threshold of 20 N has been
passed, the force is measured over a period of 5
seconds. During this time the message “Measure-
ment - Please wait” is displayed.

Once measuring has been completed, the
force/time graph is analysed automatically and
the values that are relevant to the standard are
determined.
•Display measured values
Following evaluation, the course of the force over
the measurement period (5secs) is initially dis-
played and the dynamic force Fd (peak force) dis-
played as a value.

Once the third measurement has been taken, the
totals of 3 individual measurements required for
the normal measurement have been made. If but-
ton F3 is now actuated, the mean values of the 3
individual measurements are displayed. The mean
values are identified by the addition of an “m”. But-
tons F1 and F2 do not have any function as the
graphic representation of the mean values makes
no sense.
If the mean values are displayed, the display
mode can be cancelled using F3.

4.3 Storage of the Measurement Data and Graph via a Personal Computer
The KMG-2000 G can be connected to any normal PC via a data link (USB). To do this,
the cable supplied is connected to the USB jack on the KMG-2000 G and to a USB inter-
face on the PC. Before data can be read off the KMG-2000-G the device must be switched
on and the ‘KMG-VD 2005’program on the computer which has been connected up must
be started. The software tests the connection and alerts you to any mistakes in connection
or malfunctions.
The KMG-2000 G can store a total of 500 graphs (equivalent to 166 normal measurements
with 3 individual measurements). The data is preserved, even after the device has been
switched off, with the result that the force graphs can also be read off the KMG-2000-G
during a subsequent period.
The individual functions can be called up via the program menu of the software. You can
find further explanations in the online help.

5. Menu Options
5.1 General Advice
The function keys F1, F2 and F3 are used for calling up menu functions and for operating
the device. The function of the keys is given by the symbols F1, F2 and F3 on the display.
If keys are not represented by these F symbols on the display, then those keys that are not
represented have no function or all keys have the same function. For approx. 5 seconds
after switching on the KMG a menu is displayed allowing “Options” and “Language“ to be
selected.
F1: Options Call up menu for settings
F2: New NM Initiate new normal measurement
F3: Activate Activate measuring
The menu points “New NM” and “Activate” have already been explained in Section 4.
5.2 “Options” Menu
The various options can be selected one after the
other via button F1. F2 activates the option dis-
played.
The number of the current option of a total of 6 is
displayed top right.
5.2.1 Option 1: Activation Mode
In the activation mode the type of “ready to meas-
ure” mode can be set. Button F1 switches the activa-
tion mode between “Automatic” and “Manual” and
switches back to the main menu. The illustration
shows that the “Manual” activation mode has been selected. Button F3 cancels the activa-
tion menu.
“Auto” Activation Mode: After every measurement the device is automatically switched
to “ready to measure”. As soon as a force > 20N acts on the test surface, a new force/time
graph is plotted and then the current graphic is displayed and the measured values stored.
This mode is used to record several measurements one after the other which should be
triggered automatically by kicking the test plate.
'Manual' Activation Mode:Prior to each new measurement the display must be switched
from showing the graph to showing the measured values using any button as desired. A
new measurement is then activated using button “F3”. At this setting the measurement of
the force cannot be triggered inadvertently by kicking the test plate.

6. Warning and Error Messages
6.1 Battery Monitoring
Whilst in operation the state of the rechargeable
battery is checked. If the battery is really low, the
following message appears:
With the present level of charge further measure-
ments can still be made.
If the “batteries low” message appears, the
accumulators are depleted and must be charged up.
Changing batteries is not necessary as the device con-
tains 2 rechargeable batteries. Changing batteries is only required in the event of the bat-
teries having sustained damage.
As the batteries are monitored by an integrated charging regulator whilst charging and dis-
charging, exchanging the batteries is only to be expected at the end of their useful life
(which is several years).
Charging of the batteries is essentially carried out via the USB jack of the KMG.
3 charging modes are provided for in this connection:
a) The power pack included is fitted with a USB jack.
b) The measuring device is connected via the USB cable to an adaptor used for car ciga-
rette lighters
c) The KMG is charged whilst the USB is connected to a computer via the USB interface.
Charging Adaptor for Mains Operation (230V) and Car Power Supply (12V)
The shortest charging time is achieved using the plug-in power unit. If the batteries are flat,
the charging time is approx. 3 - 4 hours.

The device has a measured-value memory capable of storing a total of 500 graphs.
This means:
a) 166 normal measurements @ 3 individual measurements
b) All 500 ‘normal measurements’ @ 1 single measurement
c) Other combinations of normal/individual measurements
6.3 Memory Space Empty
If, on the menu in 5.2.3, Check on Measured Values

no data is found in the memory bank, the following
message appears:
6.4 Device Still Loaded
In case the KMG is still loaded with a force higher
than 50N if the measurement is started manually the
display will indicate the following message:
By pressing the key F3 the measurement can still be started ignoring the current load.
However in this case the measurement accuracy will not be granted!
If this warning is indicated without a load on the measurement area, the force gauge
should be sent for maintenance to the GTE service department.

3.2 Measuring Points
A measuring point is the place where the measurement of entrapment forces
at doors must be made. Three (3) measurements must be taken at each
measuring point. The mean average value obtained at each point has to
meet the specified requirements. In the following, measuring points are de-
fined for different door types, taking into consideration:
- Opening width:
Opening width is the clear distance between the primary closing edge and
the counter closing edge i.e. between the leaf and surrounding solid parts.
- Direction of measuring force
Direction of measuring force is parallel to the line of application of the spring
force of the measuring instrument effected by the leaf during the process of
measuring. The line of application synchronises with the centre line of the
spring inside the measuring instrument, it also passes the centre points of the
head of the measuring instrument.
3.2.1 Sliding door
On a sliding door, the entrapment forces will be measured on both primary
closing edges and rear edge, as follows:
3.2.1.1 Measuring between the primary closing edge and the counter closing edge
should be done in reference to figures 1 and 2 below:

3.2.1.1.1 Measuring Points
Measurement of forces shall be carried out at the height of
- 50 mm above the lower edge of the door,
- the middle of the primary closing edge, or, at a height of 2500 mm
above the floor in case that length of the primary closing edge is
greater than 5000 mm,
and
-300 mm below the upper edge of the door leaf, or, at a height of 2500
mm above the floor where the length of the primary closing edge is
greater than 2800 mm,
and at the opening width of
- 50 mm
- 300 mm
and
500 mm between the primary and the counter closing edge.
3.2.1.1.2 Direction of measuring force
The forces must be measured parallel to the direction of movement of the
primary closing edge.
3.2.1.2 Measuring between the rear edge of the leaf and sourrounding solid parts.
Measurements should be taken between the rear edge of the leaf and sour-
rounding solid parts in the same way as for the entrapment forces between
the primary and counter closing edges (3.2.1.1.).
The opening width should be chosen between the most prominent parts on
the rear edge of the door and those on its surroundings.
