9.1.2 Important Note

When transforming an LFG to an MFG model, corresponding calibration data must be transferred from
the measuring computer of the light weight deflectometer to the Bluetooth ® load plate as well, as des-
cribed in the following section.

9.1.3 First Steps

Before establishing common applications between light weight deflectometer 'TERRATEST 6000 BLE'
and 'TERRATEST' App, electronics of the Bluetooth ® transmitting unit in the load plate must be prepared
for the App. For this purpose, calibration data of the instrument must be transferred from the measuring
electronics to the Bluetooth ® load plate. Required settings for LFG (10 kg loading assembly) have been
established at factory during each calibration by TERRATEST . This step is also required whenever chan-
®
ging the loading assembly (10 kg or 15 kg).
First switch ON Bluetooth load plate by pressing its green button. The load plate performs a self-test, after
®
completion the LED is lit in red.
Now switch ON the measuring computer by long pressing 'START' button. The display of 'TERRATEST
5000 BLU' automatically changes to 'STATUS REQUEST'. As long as the Bluetooth connection to
®
Bluetooth load plate is established, an acoustic sonar signal sounds. Completion is signaled by voice
®
message 'Bluetooth OK, start measurement', and the 'magic eye' of the Bluetooth load plate is lit in blue.
®
When changing an application of a 10 kg or 15kg load assembly, first set the corresponding falling weight
at the measuring computer (refer to section 'Type LFG/MFG' (page 56), otherwise preform the following
steps:
Press 'SELECT' to gain access to the main menu and then once more to choose by arrow menu point
'LOAD HEAD' Enter this menu by pressing 'START' button (SET). Now press 'PRINT' button twice to make
appear menu point 'SEND DATA TO HEAD'. Press 'SELECT' to choose by arrow menu point 'SEND DATA
TO HEAD', so the calibration data of the currently selected load assembly are transferred to the Bluetooth ®
load plate. This is indicated on display by a short message 'DONE'. Press 'RESET/OFF' button (EXIT) to
return to 'STATUS REQUEST', and then once more to switch OFF the measuring computer. Switch OFF
the Bluetooth ® load plate by pressing its green button.
This way the calibration data have been changed to the currently used load assembly.
