AIM 2 Operation Manual
Performing a Cable Resistance Test
You can use the AIM’s Cable Resistance test feature to help determine whether there is a
problem with a cable used in the distribution network. To complete this test, you must use the
25 Ω Cable Test Load (provided with the AIM). By placing the Cable Test Load on the end of a
cable, you can determine the resistance value for the
cable. A high resistance value indicates that the cable
may have been inadvertently cut. A low resistance
value indicates that the cable may have a short.
1. Set up the job for the installation. See the
Starting a Job section in Chapter 5.
2. From the HOME screen, press TEST to go to
the TEST screen.
3. Highlight Cable Resistance Test and press
SELECT to go to the CABLE RESISTANCE
TEST screen.
4. Connect the 25 Ω Cable Test Load to the AIM
ODU F connector.
5. Press NEXT to conrm the resistance of the
Cable Test Load.
If the resistance is outside of the allowable
range, a message appears. Perform the
following steps:
• Press RE-TEST to conrm the problem.
• If the resistance is still outside of the range,
the Cable Test Load has failed. Replace
the Cable Test Load and re-start the Cable
Resistance test.
