SXHL-100A loop resistance
The SXHL-100A is a high current loop resistance measuring instrument intended for checking conductive connection points in power electrical equipment. It can be applied to circuit breakers, busbars, and similar connections where low contact resistance is important for reliable current conduction.
The four terminal test configuration improves measurement accuracy by using separate current and voltage paths. A stable constant current source supports repeatable measurements, and the integrated LCD touch screen gives operators a convenient way to configure tests and read measured values.
