The meter is a handheld 3 1/2 digital multimeter for measuring DC and AC voltage, DC and AC current, Resistance, Diode, Transistor and Continuity Test with battery operated. Special models also can be used for testing freguency, temperature, capacitance and NCV.

• Accuracy is specified for a period of one year after calibration and at 18℃ to 28℃(64℉ to 82℉) with a relative humidity of 80%.
• Multifunctional Multimeter - High precision with data keeping function. Portable digital multimeter with multiple functions
• Overload Protection - Use a protection circuit for resistance and frequency measurement. Designed to be a practical tool, safely troubleshoot a variety of electrical tests
• Backlight Display - Maximum display,19999 counts. Optional backlit LCD with large digits for visibility even in dimly lit areas. Data hold function keeps measurements while record
• Features Plus - For special models also can be used for testing frequency, temperature, capacitance and NCV
• Widespread Use - Auto-ranging measurement. Accurately measures such as AC/DC voltage and current,resistance,continuity,diode,capacitance,frequency/duty cycle,temperature,transistor and continuity test with battery operated
