The ES3090 is engineered for critical resistance testing in power systems and industrial applications. Its 220A max current (fast mode) and ±0.15% accuracy make it ideal for high-voltage circuit breakers, welded components, and conductor loops. Features include auto-shutdown, temperature monitoring, and simple tap-style test leads (3m length, <10mΩ resistance).
