Portable Falling Weight Deflectometer

Light Falling Weight Deflectometer

 „TERRATEST 3000“

The Light Falling Weight Deflectometer in accordance with the german technical regulations TP BF-StB section B 8.3 can be used to obtain the dynamic deformation modulus (Evd value) for soils and stone pavements in road sites. This high-tech instrument has such features that guarantee a fast, practical and, thanks to the GPS system, precise investigation of the measuring data in road and pipe construction:

	integrated GPS system with Google®-Maps interface to determine quickly the position of the test points (patent pending)
	modern designed splashproof electronic box with a wide transparent window for the use of the device also during bad weather conditions
	practical and back-lit graphic display to view the curves during the tests
	clear control panel
	internal memory up to 2000 tests
	automatic plausibility check of the result
	audio signal
	external splashproof buttons
	first-rate plug connection thanks to the use of high quality plugs
	solid screwed safety grip with spirit-level
	ergonomic handle on the drop weight and loading plate with handy transport handles for a better carry
	user-friendly and practical software

Function

„TERRATEST 3000“ service is very user-friendly, as already during the construction and development phase we focused on the fact that wrong tests would automatically be excluded thanks to an internal plausibility check. Because of this, it´s guaranteed that also inexperienced people can immediately use the device and carry out precise measurements right after a quick training given by our qualified technicians.

The test execution described below shows how simple and fast it is to take measurements that can be immediately printed through the integrated mini printer and saved on the chipcard (automatic safe in the internal memory) in order to take afterwords prints also from your PC.

The practical and back-lit graphic display guides you in a very easy and clear way through the different applications and allows you to work also in bad visibility conditions.

Make sure the plate perfectly adheres to the ground. If necessary use the plate or other auxiliary tools to flatten the ground. At the start, „TERRATEST 3000“ checks the sensor connection, the battery charge, the chipcard and the GPS system and displays their status. By pressing again „START“ you automatically enter into the measuring menu and you will be asked to take the 3 preconsolidation tests and then the 3 measurements After each test, the display shows the displacement and the curves. After the third test it displays also the Evd value. The control panel is well structured and easy to use. Thanks to the back-lit display it´s easy to follow the instruc­tions. After the test, it displays the 3 displacement curves with the Evd value. sumber: http://www.terratest3000.com/english/function.html

Insert the cable and turn the electronic box on. Confirm the status query with the button „START“.

Follow the instruction: take first 3 preconsolidation tests and then 3 measurements.

Both the measuring and Evd data will be displayed. The tests are saved and can be printed later on.
