Select the resistance range and basic accuracy that match your test, then compare reading speed, four-terminal connections and comparator functions. Temperature measurement, compensation and low-voltage modes vary by model, so review the model table before choosing a configuration. For repeated inspection, consider setup memory, communications interfaces and test leads alongside the measurement specification.
