HP-25 Cable Tester


Handheld cable tester for finding common PROFIBUS cable faults



This compact handheld device checks for the most frequently found cable connection faults seen with PROFIBUS Decentralised Peripherals (DP) wiring between pairs of 9-pin D-sub PROFIBUS plugs.


HP-25 Cable Tester


The software checks for open lines, short circuits and crossed connections, reporting any such failures on a red background, with a sound signal and text details shown on the front panel colour display. Correct connection test results are reported on a green screen, with a different sound signal and show the number of activated terminator switches detected on the tested cable. If more than two terminators are detected, this is reported as a fault.


The HP-25 Cable Tester can detect:

• Open lines

• Short circuits between green and red A & B wires

• Short circuits between A or B and the shield/screen

• Crossed connections of the A & B wires


In addition to connection testing, this unit allows test tone output onto the PROFIBUS A-line, to enable clear separation of IN and OUT cables at a remote location before connection to plug or another unit. The correct orientation of cables within all PROFIBUS plugs and devices is important. A tone detector probe is included for the identification of these signals as well as a separate tone generation module for tracing LAN and telecom wiring. Both modules are powered by button cells which are provided.
