Model: A1X Maximum count: 1999 DC voltage: 0~520V (DC mode), 0.5~520V (auto mode), resolution: 0.001V, accuracy: (0.8%+3) AC Voltage: 0~520V (DC mode), 0.5~520V (auto mode), Resolution: 0.001V, Accuracy: (1.2%+5) Resistance: 0.0~19.99M, Resolution: 1, Accuracy: (1.2%+5) Capacitance: 1nF~1999F, Resolution: 0.01nF, Accuracy: (3.5%+8) On-off: when the measured resistance <50Q, the buzzer sounds Diode: less than 3V diode automatic identification Automatic shutdown: 15 minutes Non-contact voltage detection: Zero fire wire discrimination: Flashlight: Battery: Built-in 400mAh 3.7V lithium battery Charging interface: Type-C Features: 1. Red and green large screen backlight: red and green large screen display, the top lighting at the same time lit up fearless dark working environment 2. Lithium direct charging convenient and more worry-free: built-in 400mAh lithium battery, the use of Type-C charging cable, support for fast charging 3. Non-contact zero fire line discrimination: insulation operation, safety check electricity, sound and light alarm, two-color display, signal weak screen green is zero line, signal strong screen red is fire line 4. Daily electrical testing: to determine all kinds of circuit problems, lack of phase (zero / ground) short circuit / disconnect / distinguish between inductive electricity / leakage / check the breakpoints 5. Electronic maintenance components detection: can detect resistors / capacitors / diodes / fuse, etc. Package Includes: Standard Version: 1x Host 1x Manual 1x Meter pen Advanced Version: 1x Main unit 1x Manual 1x Watch pen 1x Storage bag
