characteristic; 1. Dual Mode: Multimeter supports auto mode and manual mode. Auto mode can automatically measure AC / DC voltage, resistance and continuity. 2. Bright LED Flashlight: LED flashlight lets you test efficiently and comfortably anywhere, indoors and outdoors, day and night. 3. Live / Neutral Wire Check: Safe and easy to distinguish the live / neutral wire by comparing the strength of the detected voltage, the wire that detect the stronger voltage signal is live wire. 4. LCD Display: Greatly enhance the reading experience, the lighted up numbers and letters make it very easy to read, even in bright sunlight or poor light. 5. Easy to use: Insert the red test lead into the "INPUT" terminal, black test lead into the "COM" terminal. The AC and DC voltage, resistance and continuity can be measured directly after startup. specification Temperature: 0~40 / 32~104 Storage Temperature: -10~60 / -4~140 Operating Altitude: ≤ 2000m Battery: 1.5V AAA x 2 (Included) Automatic Measuring Range: YES Full Measuring Range Overload Protection: YES Flashlight: YES V-Alert (NCV): YES Live / Neutral Wire Check: YES Breakpoint Locate: YES Automatic Identification: YES Item Size: 12.7*4.2*2.5cm / 5.00*1.65*0.98in (L*W*H) Packing Size: 16.5*7.3*3.8cm / 6.50*2.87*1.50in (L*W*H) Net Weight: 67g / 2.36oz ( without battery Gross Weight: 157g / 5.54oz Function Range Resolution Accuracy Input Impedance Maximum Input Voltage Red Backlight Alert DC Voltage 0V~500V (DC Mode) 0.5V~500V (Auto Mode) 0.01V ±0.8% + 3 counts 1MQ 500V DC & AC (RMS) >90V AC Voltage 0V~500V (AC Mode) 0.8V~500V (Auto Mode) 0.01V ±1.2% + 5 counts 1MQ 500V DC & AC (RMS) >90V Resistance 0Ω~10MΩ 1Ω ±1.2% + 3 counts / / / Frequency 40Hz~1000Hz 0.1Hz ±2.0% + 3 counts / / / Package List: 1 * Multimeter 2 * Test Lead ( Red & Black ) 1 * Screwdriver 2 x 1.5V AAA 7# battery 1 * Instruction Manual ( Chinese & English )
