The meter is a hand held 3 1/2 digital multi-meter for measuring and AC voltage, and AC current, Resistance, Diode, Transistor and Continuity Test with battery operated. For 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 relative humidity to 80%.Features:Multifunctional Multimeter - High precision with data keeping function. Portable digital multimeter with multiple functions.Overload Protection - Use 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/ voltage and current,resistance,continuity,diode,capacitance,frequency/duty cycle,temperature,transistor and continuity test with battery operated.Specifications:Material: ABSColor: Red / Blue / Orange (optional)Maximum voltage between terminals and earth ground: 600V or 600V ACFuse protection: F 250Ma/250V Self-restoring fuse9V battery, NEDA 1604 or 6F22Display: LCD, 1999 counts, updates 2-3 times per secondMeasuring method: Dual-slope integration A/D converterOver range Indication: Only figure “1” on the displayPoladty indication: “-”display for negative polarityOperating Environment: 0 to 40℃Storage temperature: -10 to 50℃Low battery indication: appears on the displayVOLTAGE: Overload Protection: 250V rms for 200mV range, and 600V or rms AC for other ranges.AC VOLTAGE: Overload Protection: 600V or AC rmsCURRENT:Overload Protection: 250V or AC rms for all ranges.Overload Protection: F250Ma/250V fuse.
