The KMG-2000-G force-measuring device is used for the routine, on-the-spot checking of 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. The measured values can be transferred to a laptop or PC via the built-in USB interface. By using the KMG-VD 2005 software, an exact analysis of the measured values and possible target deviations can be carried out. The required software can be ordered as an accessories. The centerpiece of the KMG-2000-G contains an LCD display, on which all the measured values, the force curves, the measured-value memory management function, and user guidance are displayed.

Menu Options

6.1 General Notes
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 these keys 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.

6.2 “Options“ Menu
The various options can be selected one after the other via button F1. F2 activates the option displayed. The number of the current option of a total of 6 is displayed top right.
6.2.1 Option 1: Activation Mode
In the activation mode the type of “ready to measure” mode can be set. Button F1 switches the activation 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 activation menu. Activation Mode “Auto ”: 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 another which should be triggered automatically by hitting the test plate.
Activation Mode „Manual“: 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 hitting the test plate.
6.2.2 Option 2: Delete Mode
In order to prevent accidental deletion, button F2 must be pressed for longer than 3 seconds.
The following delete functions can be selected on the delete menu:F1: entire memory is deleted
F2: last individual measurement is deleted
F3: last standard measurement along with its 3 individual measurements is deleted.
After actuating one of the selection buttons relating to the type of measurement values, you are asked once more in a further menu whether the measured values selected should be deleted.
F1 = Yes
F3 = No
By actuating F1 the data selected will be deleted.
6.2.3 Option 3: Check on Measured Values Held in Memory
By actuating button F2 the control display relating to those measured values deposited in the memory is called up.
The item stored „normal measurement / single measurement no.“ is displayed top right, e.g. in this case: 2 individual measurements within the 28th standard measurementF1 previous measurement
F2 next measurement
F3 display of the relevant force/time graph
After browsing all individual measurements the relevant mean values appear. These are identified by an “m” on the display. 6.2.4 Option 4: Lightning Adjustment
On this menu the lighting of the display can be switched on or off using button F1.
6.2.5 Option 5: Buzzer
On this menu the internal buzzer can be switched on or off using button F1.The buzzer gives an audible signal once measuring has been completed.

Measurement Preparation

7.1 Turn on the KMG-2000-G
► Press any key
 KMG-2000-G is switched on.
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 measuredvalue memory is displayed top left, e.g.:
2. Normal measurement
3. Individual measurement
7.2 Performing Measurement
A measuring operation is activated by pressing button F3. The device is now ready to take measurements. The measuring operation is started if a force > 20 N acts 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 according to the standards. The measuring points are specifically prescribed in relation to the relevant type of gate construction.
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 “Measurement – Please wait” is displayed.
Once measuring has been completed, the force/ time graph is analyzed automatically and the value relevant to the standard are determined.

Measurement Analysis

9.1 Display Measured Values
Following evaluation, the force-time graph over the measurement period (5secs) is initially displayed and the dynamic force Fd (peak force) is displayed as a value.
Button F1 : To switch between “normal display“ (5 sec. measuring range) and „zoom display“ of the dynamic range (1sec measuring range)
Button F2: To switch to display of 4 measured values:

Button F3: Cancellation of display mode
Once the third measurement has been taken, the totals of 3 individual measurements required for the standard measurement have been made. If button F3 is now actuated, the mean values of the 3 standard measurements are displayed. The mean values are identified by the addition of an “m”. Buttons F1 and F2 do not have any function as the graphic representation of the mean values doesn‘t make sense. If the mean values are displayed, the display mode can be cancelled using F3.

9.2 Further Measurements
you can return to the main menu by actuating button “F3” and to the “Start F>20N” display by actuating button “F3” once again

9.3 Storage of the Measurement Data and Graph via PC
The KMG-2000-G can be connected to any 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 interface on the PC. Before data can be read from the KMG-2000-G the device must be switched on and the „KMG-VD 2005“ program on the computer has to be started. The software tests the connection and alerts you in case of mistakes in connection or malfunctions.
The KMG-2000-G can store a total of 500 graphs (equivalent to 166 standard 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.

Warnings and Error Massages

10.1 Battery Monitoring
Whilst in operation the state of the rechargeable battery is checked. If the battery charge is low, the following message appears:With the present level of charge further measurements can still be made.
If the “batteries low” message appears, the batteries are depleted and must be charged up.Changing batteries is not necessary as the device contains 2 rechargeable batteries. Changing batteries is only required if the batteries are damaged. As the batteries are  monitored by an integrated charging regulator whilst charging and discharging, 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. Three charging modes are provided for in this connection:

• The included power supply is equipped with a USB jack.
• The measuring device is connected via the USB cable to an adaptor used for car cigarette lighters.
• The KMG is charged whilst the USB is connected to a computer via the USB interface.

The shortest charging time is achieved using the power supply unit. If the batteries are empty, the charging time is approx. 3 – 4 hours.
Operating display:
a) without KMG connection: LED green
b) charging process: LED red
c) charging process completed, holding charge: LED green for 19 secs and red for 1 sec.
The average power consumption in case of an unilluminated display is approximately 20 mA, and in case of an illuminated display approximately 40 mA. This gives an operating life of approximately 80 hours in normal display mode and approx. 40 hours in the case of an illuminated display.
10.2 Memory Space
Whenever the KMG switches to the “ready to measure” mode while the memory is full, the following message is displayed:
After actuating F1 branching off to the options menu
Notice: The device has a measured-value memory capable of storing a total of 500 graphs. This means:
a) 166 standard measurements à three individual measurements
b) 500 standard measurements as single measurement
c) other combinations of standard/individual measurements
10.3 Memory Space Empty
If no data is found while performing menu in 6.2.3, „Check on Measured Values Held in Memory“, the following message appears: 10.4 Device Still Loaded
If the KMG-2000-G is loaded with a force of more than 50 N when a measurement is started manually, further measurement is possible (F3 key), but the measurement  accuracy is no longer guaranteed. The following message is displayed:By pressing the F3 key, the measurement can be continued despite the basic force. If this warning is indicated without a load on the measurement area, the force gauge should be sent for maintenance to your service department.

Calibration

As a demand of EN 12453 and EN 16005, each force-measuring device has to be sent to for calibration at least once a year.

Disposal

Send the KMG-2000-G back to the manufacturer at the end of its useful life. This ensures environmentally friendly disposal of all components.
