APLAB Model 3039-I cable fault locator is portable, rugged, simple to operate and which can taste, locate & display on the CRT the short & open type of faults in long run of coaxial and twisted pair in telephone and other communication application. It measures the distance to the faults, directly giving a digital readout. It also gives an insight into the joints, cable changes and faults aiding location of the fault.
Model 3039-I works on the principle of Time domain reflectometry (TDR) and locates cable faults upto an approximately distance of 5 Km & above with an accuracy of ±1%. The velocity of propagation (VOP) V/2 for each cable type is set on a three digit thumbwheel switch. It sends out an electrical narrow pulse of 35 to 1800ns width depending on distance to be covered with a fast rise time. The pulse is then reflected back to the unit from the cable impedence mismatch or the fault location. The distance of the fault is then computed automatically and indicated in meters or feets on a large LED display which will eliminate the manual calculations. Fault type is also identified by the graphic display of the shape of the reflected pulse. It is simpler to operate and less error prone than manual bridge technique.
It being light weight and portable can be carried on the field and can be operated for at least 8 hours on the internal rechargable batteries. Model 3039-I is provided with rechargeble batteries and an in built battery charger.
