BA427 "James" Connection Tester

 

Page Summary, TL;DR

What it does: The BA427 is designed to test cables, harnesses, and prefabricated modular wiring looms to comply with BS 8488 (BS8488:2009+A1:2010 ) British Standard requirements for safety testing.

What it tests: Cable resistance (using precise 4-wire Kelvin method), continuity, shorts, and insulation. Can handle up to 1500V DC testing depending on model.

Key capabilities:

·         High-current testing capability (up to 10 amps) that most standard testers lack
·         Measures cable resistance with 1 milli-ohm resolution using 4-wire testing
·         Tests insulation resistance at 500V (must exceed 20 Meg Ohms per BS 8488)
·         Checks for continuity, shorts, and resistance
·         Windows-based software with user-friendly interface
·         Results stored in Access database format for quality control tracking

Technical Specifications:
·         Compatible with Windows11
·         USB connections for easy setup
·         Modular design: each module has 8 connections (16 test points)
·         Expandable from minimum 8 to maximum 24 connections
·         Low current continuity test at 5V DC
·         High current resistance test at up to 12V DC with 1-10A
·         Insulation testing from 50V to 1000V DC
Productivity Features: Includes footswitch for hands-free testing, printed results, and labels.

Bottom line: The system provides improved quality control, cost savings, fault identification for rework, and full traceability of test results. It's specifically designed to fill the gap where standard harness testers cannot provide the required 10-amp testing current mandated by BS 8488..
