Abstract
A handheld maintenance tool operates to detect the existence of a fault in a communication line or bus, including detecting short circuit or other low impedance faults, open circuit or other high impedance faults, etc. Additionally, the handheld maintenance tool may operate to detect an approximate location of a fault within the communication line with respect to the handheld device, to thereby enable an operator or maintenance person to more easily find and repair a detected fault.
