 Features:

The 9999counts is a pocket-sized 3 9/10-bit automatic digital instrument. Is a stable performance, high precision, high reliability clear readings, and overload protection . With AAA 1.5V battery-driven,the instrument uses a large-screen LCD display, boost power supply, even in the 2.3V low battery edge, it can guarantee the backlight high brightness, the table is easy to carry, is a vast number of users extremely like the instrument, the backlight can be bright can be automatically turned off after 15 seconds. This series of instruments can be used to measure the DC voltage and AC voltage DC current and AC current,resistance,capacitance diode,continuity test, frequency measurement and true RMS measurement and other parameters. Is an ideal tool for the laboratory, factory, radio enthusiasts and families.
