  • Page 31: Maintenance Of Tc-5942B

    5-1 Maintenance of TC-5942B Maintenance of TC-5942B TC-5942B is designed and built for long life and easy maintenance. Optimal RF shielding is obtained using a wire mesh gasket between the case and lid. It must be checked periodically for damage or excessive wear that would compromise the seal. Pressure on the gasket by the lid results in a proper RF seal.
  • Page 32 Periodic cleaning of the aluminum contact surface where the gasket touches is important for optimum shielding performance. Figure 5-2 TC-5942B RF gasket Maintaining the shielding effectiveness.  1. RF shielding effectiveness of TC-5942A/B/BC depends on mechanical contact and will degrade with its use. Typical degradation is shown in Table 1.

  • Page 33: Performance Test

    5-2 Performance Test Performance Test TESCOM Shield Boxes are precision RF devices built very sturdy. Their electrical performance can, however, deteriorate with mechanical damages. Worn out shielding gaskets, as well as metal corrosion or oxidation at the lid contact, can significantly reduce the effectiveness of the Shield Box.
