The Yokogawa 73204 is a 3.5-digit handheld digital multimeter engineered for field service, maintenance, and general electrical troubleshooting. Its 4300-count LCD display delivers readable measurements across DC/AC voltage, current, resistance, continuity, and diode test functions. Mean-value detection with auto-ranging capability provides rapid, accurate readings without manual range selection. The instrument incorporates overload protection, over-range warning, and auto power-off to extend battery life during extended field deployments.
