3.2.15.4 INSTALLATION INSTRUCTIONS 1
S-DG BT mechanical depth gauge
To help ensure the exact screw-in depth and a proper compressed sealing washer are obtained , the S-BT studs have to be installed with the S-DG BT mechanical depth gauge for M8 or M10 / W10 S-BT fasteners . With this gauge the screw-in depth can be adjusted in a range of 0 - 1.5 mm ( 3 steps , 0.5mm per step ).
The S-CC BT calibration card is needed to check the initial stand-off of the S-BT stud and to adjust / calibrate the S-DG depth gauge . After finding the right adjustment level for the S-DG depth gauge , the gauge can be adjusted to the level number shown in the calibration card accordingly and the studs can be installed without additional check of the S-DG depth gauge .
Design and functionality of the mechanical calibration card S-CC BT
The depth gauge has to be re-adjusted ( calibrated ) at following times :
• Start of the installation process
• Change of the working position ( upwards , downwards , horizontal )
• Installer change The lifetime of the S-DG BT depth gauge is ≥ 1000 settings .
