Two-Wire irrigation systems require a different set of tools to diagnose electrical problems, and decoders in these systems run on milliamp-sized current. That's why a clamp multimeter that measures milliamps, such as the Armada Pro93 True RMS 2-Wire Milliamp Clamp Multimeter, is perfect for the job. The Pro93 also utilizes True RMS technology. True RMS stands for "Root Mean Squared", which is an obscure term if you're not an electrical engineer. But in practice, it means the Pro93 uses the most accurate measuring system available, rather than conventional averaging clamp multimeters. That is especially important with modern LED lighting that requires accurate loading to ensure that fuses aren't blown.
