T M switch to T for two way communications c When operating on low voltage or dry circuits a minimum of three volts DC talking battery is required Page 4 5 07 Troubleshooting The following troubleshooting procedures are based largely on the audible click heard in the receiver of the TS21 when the two Test Set leads are placed on battery potential and ground respectively or across the terminal of an electrically charged capacitor These clicks and other sounds can greatly help a skilled crafts person in locating open circuits shorts crosses and grounds a To locate a short circuit open one side of the telephone line and place the test set in the loop one lead to each side of the opened line On the CO side of the fault a loud click will be heard on the field side of the fault no click will be heard b Locating an open circuit is done by bridging the test set across the circuit line one test lead on tip the other on ring Moving away from the CO the fault is at the point where the loud click disappears c Continuity of each side of the loop may be verified by placing one of the line leads on a local ground and the other on the conductor in question On a good ring conductor a click will be heard on a good tip conductor an inductive hum will be heard due to the difference in ground potential between the CO ground and the local ground Note For a full discussion on these troubleshooting procedures
