Mechanical design
The unit is portable and has been designed for use on site.
It consists of two parts: plastic housing and aluminum plate. Both are connected
via a snap-on mechanism and can easily be separated. The housing accommo-
dates an electronic circuit board, setting buttons, LCD and a connecting cable.
The separate cables have a connector at one end and ferrules or a 6-or 7-pin plug
at the other. All wires are color-coded and labeled (refer to "Technical data").
The cable is connected to the handheld tool via the plug on the bottom of the
device.
