The HHM8229 digital multimeter can perform measurements of AC/DC voltage and current, resistance, frequency, duty, capacitance, as well as continuity and diode test. Both the reading and unit of measurement are displayed on the LCD, and includes both autorange and manual operation. Auto range and manual range are both available. The HHM8229 is equipped with auto power off function, reading hold function, and relative measurement function.
