| Description | The Wire Mapper Pro Model CA7028 is a hand-held structured cable mapping and troubleshooting tester designed for use on UTP, STP, FTP, and SSTP cabling equipped with RJ-45 connectors and wired to either TIA568A/B ISO11801 and EN 50137, USOC or ISDN specifications. It detects open circuit pairs, shorts, crossed wires, crossed pairs, reversed pairs, split pairs and shield faults. The Model CA7028 also has the ability to identify telephone and data lines. If the main unit is plugged into an operational RJ-45 socket, it will give a continuous warning tone and display if a telephone voltage is present on any of the pins. If the Service Detect key is pressed, it will check and display telephone, 10BaseT, 100Mbit+ and token ring active service. | | | | | |
| Content | | | The Ground Resistance Tester Model 6416 measures ground rod and grid resistance and impedance without the use of auxiliary rods. Clamp-on ground resistance testers can be used in multi-grounded systems without disconnecting or de-energizing the ground system under test. The Model 6416 simply clamps around the grounding electrode or conductor and measures the resistance to ground. By performing measurements on intact ground systems, the user also verifies the quality of the grounding connections and bonds. Resistance and continuity of grounding loops around pads and buildings may also be measured. | | | The Ground Resistance Tester Model 6418 measures ground rod, busbar, and grid resistance and impedance without the use of auxiliary rods.
