Accessories such as probes, crocodile clips and long reach test probes are interchanged many times during a single day of use and it is inevitable that over time, contact resistance at the point of connection will increase causing the user to doubt the result being displayed.
It is recommended that care is taken to regularly clean and lubricate test leads, but it is inevitable that leads will need replacing over the life span of a test instrument. We have a wide range of test leads, clips and probes available for your tester from manufacturers including Megger, Kewtech, Metrel, Martindale, Dilog, Extech and many more.
