User manual

REED ST-9809 is a digital AC clamp meter that can be used for various electrical measurements, including AC current, AC voltage, resistance, and continuity. It features a large 30mm diameter clamp jaw, a 3 ¾ digit LCD display, and a bar graph that displays 20 times per second. The ST-9809 has a wide range of features, including a filter circuit that eliminates the effect of high-frequency noise and harmonics, a max/min hold function, a data hold function, and a relative measurement function. It also has a low battery indicator and an auto power-off function to conserve battery life.

User manual

REED ST-9809 is a digital AC clamp meter that can be used for various electrical measurements, including AC current, AC voltage, resistance, and continuity. It features a large 30mm diameter clamp jaw, a 3 ¾ digit LCD display, and a bar graph that displays 20 times per second. The ST-9809 has a wide range of features, including a filter circuit that eliminates the effect of high-frequency noise and harmonics, a max/min hold function, a data hold function, and a relative measurement function. It also has a low battery indicator and an auto power-off function to conserve battery life.
