A3006 Digital Pen Type 4000 Counting AC/DC Voltage Meter Tip Test Zero Neutral Line High-Precision Electric Tools

This pen-type digital instrument is a small 4000-count true RMS automatic scanning digital device. Based on the differences in voltage and resistance, users can select the function without turning the dial, as it has an automatic recognition measurement function. It achieves stable performance, high accuracy, high reliability, clear readings, and overload protection. This instrument is charged by AAA 1.5V low batteries. It features a large-screen liquid crystal display, and the beautiful backlight makes the display clear and convenient, and is loved by most people. This new type of instrument can automatically identify direct current voltage, alternating current voltage, resistance, continuity, without any selection. In addition, it has a manual switching function to measure electric field induction and neutral line discrimination. Due to its outstanding performance, it will become an ideal tool for radio enthusiasts and families. 
 

1.Correct Wiring: When connecting the wires, it is necessary to pay attention to the voltage and current  of the circuit under test, select the correct measurement port, and ensure that the connections are secure. Incorrect or loose wiring may result in inaccurate measurement results or damage to the . 
2. Preventing Electric Shock: When measuring the circuit, make sure the circuit is disconnected. Avoid touching exposed wires or circuit boards with your hands to prevent electric shock accidents. When measuring high voltage or large current, safety precautions should be taken even more seriously. 
3. Do not change gears during measurement: When measuring a specific amount of electricity, do not change gears simultaneously, especially when measuring high voltage or large current. If you need to change gears, disconnect the probe first, then change gears and measure again.
