Component Testing

CAUTION:

Refer to Test Probe Caution

NOTE:
  • Before testing the coax cable, check the cable's exterior for being pinched, cut, damaged, or having loose connections at the components, all of which can cause reception issues.
  • To prevent an incorrect reading when testing the center coax terminal, use care not to ground the test probe on the outer housing/shield.

Coax Cable Test

  1. Test for less than 5 ohms between the test points: Coax Cable Center & The other end of the circuit
    • If 5 ohms or greater 

      Test or replace the component: Coax Cable

    • Go to next step: If less than 5 ohms 
  2. Test for greater than 5 ohms between the test points: Coax Cable Outer Shield & The other end of the circuit
    • If 5 ohms or greater 

      Test or replace the component: Coax Cable

    • Go to next step: If less than 5 ohms 
  3. Test for infinite resistance between the test points: Coax Cable Outer Shield & Coax Cable Center
    • If less than infinite resistance 

      Test or replace the component: Coax Cable

    • Go to next step: If infinite resistance 
  4. All OK.
