A test fixture designed to measure selected electrical parameters of a wax which is utilized as a dielectric in telephone transmission lines. The test fixture is mounted on top of and plugged directly into a commercially available Q (quality factor) meter. A high Q coil is also mounted on top of and plugged directly into the Q meter. A T-shaped ground shield plate separates the test fixture from the coil, and also covers the front of both components to shield them from stray capacitance and interference from operator proximity and system configuration.
