Features: Color display multifunction test instrument, using imported chip, ABS flame-retardant housing, not easy to deforms, wear resistant. Can be automatically calibrated, can automatically identify the foot position and can be graphically displayed, large screen display, easy to read and observe. With USB charging interfaces, LED indicator, receiver window, builtin lithiums battery, long life. With high-precisions measurement capability, can provide accurate measurement result, can better evaluate the performances and characteristics of electronic components. It can be used to measure the parameters of electronic components, such as: inductance, capacitance, resistance, diode/triode, light-emitting diode and other components.
