SCHAFFNER has released the WK 140 and WK 240 cable and harness testers. They are available from Power Parameters .
They provide a comprehensive service-depot and production-oriented testing facility for the location and statistical analysis of opens, shorts, and miswires. They are also capable of resistor, capacitor, diode and function tests of keyboards and relays.
The testers can be easily integrated into a PC network via an optional Ethernet interface for TCP/IP. The WK 140 tester has a maximum of 384 test points. The WK 240 has up to 512 points which are expandable to 1024 points using an expansion unit. The controller hardware utilises a 20MHz CPU, and 512 Kbytes static RAM, battery-backed for 5 years minimum. A PC-card slot is available for additional storage on a PCMCIA-configured card of test programs. Two parallel and three serial interfaces are provided for the installation of printers and barcode readers. An additional interface is suitable for driving external devices such as fixtures and feeders.
