Description
The TR-MARK III 250 V supports ratio, excitation-current and phase-angle measurements for transformer verification. Automatic connection switching and vector-group detection help streamline three-phase testing. Results can be retained in internal memory and transferred for reporting. This is the portable 250 V model.
