ANENG ST210 Digital Multimeter 6000 Counts NCV Tester True RMS Portable AC/DC Voltage Meter LCD Backlight   Description:   6000 counts is a pocket-sized 3 5/6 digits true effective value automatic scanning digital meter.   No need to turn the dial to select the function, according to the input voltage/current/resistance/current difference, the meter will automatically identify and measure.   Stable performance, high precision, high reliability, clear reading, overload protection function.    Driven by AAA 1.5V battery, uses a large-screen LCD display and uses boost power supply.    Even at the edge of a 2.3V low battery, it can ensure the backlight and ultra-high brightness of the flashlight.    Easy to carry and is a favorite of most users for the instrument, the backlight can be on for a long time or automatically turn off after 15 seconds.    This series of meters can automatically identify DC and AC voltage, AC and DC current 600A, resistance, without any switching, and can also manually switch to measure capacitance, diode, continuity test, and other parameters.    A tool with superior performance. An ideal tool for laboratories, factories, radio enthusiasts and families.      Specification:   Display mode: liquid crystal display;   Maximum display: 5999 (5 5/6) digits automatic polarity display;   Measurement method: double integral A/D conversion;   Sampling rate: about 3 times per second;   Over-range display: the highest position displays "OL";   Low voltage display: ''　'' symbol appears;   Working environment: (0-40)℃, relative humidity <80%;   Power supply: AAA 2* 1.5V battery (not included)     Size(LxWxH): 176x67x33mm/6.93*2.64*1.3in     Color: Black, Red      Feature:      DC voltage DCV: yes   AC voltage ACV: yes   DC current DCA: yes   AC current ACA: yes   Resistance/diode/continuity test/capacitance: yes   Frequency F: yes   NCV: yes   Neutral/FireWire test: yes   Full unit symbol: yes   Backlight manual/automatic turn off: yes   True RMS measurement: yes   Temperature (℃/℉): yes   Flashlight lighting: yes      Technical index:   DC voltage/AC voltage automatic scanning test (DCV/ACV)   Range/accuracy  6000counts    resolution   DC/AC6V           ±(0.5%+3)      0.001V   DC/AC60V                               0.01V   DC/1000V                                0.1V   AC750V            ±(0.8%+10)     1V      Resistance (Ω)   Range/accuracy    6000counts   resolution   600Ω                  ±(0.8%+5)     0.1Ω   6kΩ                    ±(0.8%+3)     1Ω   60kΩ                                       10Ω   600kΩ                                     100Ω   6MΩ                                        1kΩ   60MΩ               ±(2.
