• Individual measurement
• StM: 2 SiM: 3
• Options: F1
• New StM:  F2
• Activate:    F3

 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).

• StM: 2 SiM: 3
• Options:  F1
• New StM:  F2
• Start:    F>20N

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 pas-sed, 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

 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:
Max. dynamic force:
Static force:
End force after 5 seconds:
Duration of dynamic force range:
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.

 Further Measurements

You can return to the main menu by actuating button “F3” and

• StM: 2 SiM: 3
• Options: F1
• New StM:  F2
• Activate:  F3

to the “Start F>20N” display by actuating button “F3” once again

• StM: 2 SiM: 3
• Options: F1
• New StM: F2
• Start:        F>20N

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 connecti-on 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

 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.
Charge batteries

• Exit: F3

If the “batteries low” message appears, the batteries are depleted and must be charged up.
Batteries  low

• Exit: F3

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 char- ging 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:

• without KMG connection: LED green
•  charging process: LED red
•  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.

Memory Space

Memory full

• Options  F1

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:

•  166 standard measurements à three individual measurements
•  500 standard measurements as single measurement
•  other combinations of standard/individual measurements

Memory Space Empty

Memory empty

• Exit:  F3

If no data is found while performing menu in 6.2.3, „Check on Measured Values Held in Memory“, the following message appears:

 Device Still Loaded

Device still loaded

• Exit:  F3

If the KMG-2000-G is loaded with a force of more than 50 N when a measurement is started manual-ly, 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.
