Tips

For best results, test cables before installation and after termination. Use the slow scan mode for detailed wire-by-wire verification and fast scan for quick pass/fail checks. Keep spare 9V batteries on hand, as the tester does not include one. When testing long runs, ensure both ends are accessible to connect the remote unit.
