New Hi-Port HP-25 PROFIBUS Cable Tester

alt





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

The software checks for and reports open lines, short circuits between cores, shorts between screen and cores, and crossed connections, reporting any such failures on a red background, with sound signal and text details shown on the front panel colour display. Correct connection test results are reported on a green screen, with different sound signal and show the number of activated terminator switches detected on the tested cable. If 3 or more terminators are detedted this is reported as a fault.


Fault details are emphasized by display of associated conductor colour information, showing green background for A line, red background for the B line and black for the cable screen/shield.


In addition to connection testing, the unit also 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 other unit. Correct orientation of cables within all PROFIBUS plugs and slaves is very important. An optional tone detector is offered for identification of these signals : this unit, as shown in following photo, includes separate tone generation module for tracing LAN, telecom or other wires. Both modules are powered by button cells which are included.

alt

This tester is only suitable for use on totally unpowered cables!


The HP-25 is supplied with silver end of cable test plug and PP3 battery, with or without optional tone detector (as in photo). A strong hard carry case is also available as an optional item (as photo).
