Hioki has announced the launch of a proprietary non-circuit breaker tripping digital multimeter design – Digital Multimeter DT4223 and DT4224. Caution is necessary when using testers to measure electrical voltages. Improperly setting the instrument to its resistance range, for example, when measuring a voltage can cause a power outage by tripping a circuit breaker or result in an electrical accident. By providing a voltage input protection function, the new digital multimeter DT4223 and DT4224 improves safety, preventing electrical accidents caused by operator mistakes and enabling greater peace of mind.
