Students Measuring Desk
The 4 mm sockets are intended for measuring of the original values. One measuring desk consists of: the universal student's base plate, the circuit diagram mask 138099250 for the specific system which is simply placed on the student's base plate, and a line with 37 poles. The right-hand line is simultaneously the line for the next student's measuring desk. Thus, only one line per measuring desk is necessary. The red sockets always have the voltage of the board terminals 30 and 15, the black sockets have ground potential. The white sockets give access for specific signals as they are available on the pins of the control unit of the original system. All test sockets are decoupled. This means that the circuit diagram base plates cannot influence each other and the control unit of the equipment is protected.
