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.
