Regularly check that the transportation lock of the drop weight is functioning
properly. If you notice signs of wear, stop using the device immediately. Send
the device back to TERRATEST for the transportation lock to be repaired or
replaced.
Put on hearing protectors before the first drop. Hearing protectors must be
worn when operating the Light Weight Deflectometer, since the noise level
may rise over 85 dB during the test. ATTENTION: Operating the device
without hearing protection can result in permanent hearing impairment.
If the status LED on the Bluetooth ® sensor dome shows green, the device is
ready for transferring data to the testing computer. Following the voice
instruction ‘FIRST PRELOAD’ and the display instruction ‘10 kg 1. Preload’,
continue with the first pre-consolidation test as follows: Take hold of the blue
safety grip at the end of the guide rod; open the release mechanism by
pushing the green start lever towards the guide rod and holding it there. With
your other hand pull up the unlocked drop weight all the way until it stops.
Fix it in place by releasing the green start lever and thus latching the drop
weight into the release mechanism. The drop weight is now fastened securely
in the release mechanism on top of the device. Open the release mechanism
by pushing the green start lever towards the guide rod, and let the drop weight
fall freely until it hits the spring assembly. Catch the drop weight immediately
after first contact and, in the same way as described above, latch it back into
the release mechanism. The status LED on the Bluetooth
® sensor dome shows
blue while transferring the data to the testing computer. The status LED
switches back to green, when the device is ready for the next test. In total, six
drops must be performed to complete the test.
After hearing the audio signal, receiving the instruction ‘10 kg 2. Preload’ on the
display of the testing computer, and hearing the voice instruction ‘SECOND
PRELOAD’, continue with the second pre-consolidation test in the same way as
described above. The testing computer will not register any drops performed before
the acoustic signal.
After hearing the audio signal, receiving the instruction ‘10 kg 3. Preload’ on the
display of the testing computer, and hearing the voice instruction ‘THIRD
PRELOAD’, continue with the third pre-consolidation test in the same way as
described above.
The device checks the results of the three pre-consolidation tests and then
progresses automatically to the main test.
After hearing the audio signal, receiving the instruction ‘10 kg 1. Test’ on the
display of the testing computer, and hearing the voice instruction ‘FIRST TEST’,
continue with the first test in the same way as described above.
After performing the first test, the device will show the settlement s4 in mm, as
well as the respective settlement curve.
After hearing the audio signal, receiving the instruction ‘2. Test’ on the display of
the testing computer, and hearing the voice instruction ‘SECOND TEST’, continue
with the second test in the same way as described above.
After performing the second test, the device will show the settlements of both prior
tests, s4 and s5, in mm, as well as the respective settlement curves.
After hearing the audio signal, receiving the instruction ‘3. Test’ on the display of
the testing computer, and hearing the voice instruction ‘THIRD TEST’ continue
with the third test in the same way as described above.
