In a method for testing an electric circuit comprising circuit subunits, the electric circuit is connected to a test system via a tester channel with a connection unit. The test device includes a nut secured to the tool display board and a bolt to be driven by the wrench for engagement with the nut. These teachings will also accommodate calculating the total LTC benefits by summing the value of the fixed annuity with the value of the fixed annuity as multiplied by a multiplier. The system is able to convert from a folded configuration into a functional configuration, which may be a chair, desk, lounge, table or stool. The operating and control devices can be arranged individually or in groups or they may be combined to units.
