Abstract: A method and apparatus for determining contact resistance (107) includes pressing a lead connector (105) to make a first contact with a metallic pad (103) and an isolated contact with an isolated metallic pad (108) located adjacent to metallic pad (103). Once the first and isolated contacts are formed, the method includes flowing electrical current at a predetermined level through the isolated contact. With the aid of a volt meter (110), voltage differential across the isolated contact is measured while the electrical current at the predetermined level is flowing through the isolated contact. The contact resistance (107) of the first contact is determined based on information obtained from the voltage differential measured across the isolated contact and the predetermined level of the electrical current. Furthermore, the contact force created at the first contact is determined based on the contact resistance (107).

Abstract: A remote power measuring device (1) is used to measure the power output of the transmission system (20). The measured power is then transmitted to a controller (5) and used by the controller (5), along with preset calibration data (41) for each power amplifier (3), to determine power output adjustment factors (22). The adjustment factors (22) are then communicated to the appropriate power amplifier (3) to adjust its output.
