【Parameter】- Test Voltage: 12-220V; Circuit Type: AC/DC; Display Mode: LED Light + Display Special Function: Zero line and live line recognition,Continuity Test.
【Quality Material】- This DC voltage tester is made of high quality plastic, insulating, sturdy and durable.
【Null Line Test】- The finger touches the direct detection button,and the voltage pen inserts the copper core into the fire wire.The value on the screen is "⚡".
【Inductance Break-point Test】- When the hand pushes the "Inductance Break-point Test"button,the slot head approaches the wire,and a "⚡" symbol appears.The slot head moves along the wire all the time. When the "⚡" symbol disappears,this is the breakpoint.
【Instructions for Use】- The AC circuit tester is suitable for direct testing of 12-220V AC and DC and indirect testing of the zero line, phase line and breakpoint of AC power. It can also measure the continuity of uncharged conductors.

【Parameter】- Test Voltage: 100-500V; Circuit Type: AC/DC; Display Mode: Neon Tube; Test Head Type: Flat head; Special Function: Slotted Screwdriver;Total Length: 130mm/5.07";Pole Length: 25mm/0.98".
【Neon Tube Light Display】- The neon tube light of the circuit pen will light when the pen detects voltage; The higher the voltage, the brighter the neon tube light.
【How to Use】- When you use the voltage test electroprobe,before testing,it is necessary to insert the screwdriver to the bottom,hold the finger against the end of the handle.The neon tube turns light when there is electricity and operate safely.
【Two Usage】- Two kinds of applications,one for measuring circuit electrical penand the other for screwdriver.Two types of screwdriver tips on the both end of metal rod-slotted and cross-recess.When you pull out the metal rod,please insert the rod to the deepest position to make full contact.
【Warm Tips】- AC circuit tester light detector is for indoor use only and to avoid strong light.

【Parameter】 - Product model:MF110A. Humanized design, self-locking bracket, stable bracket, can shift bracket angle arbitrarily
【Function】- The multimeter measures AC current, AC and DC voltage, DC resistance, and also provides diode test, battery power test, temperature measurement, capacitance measurement, LI measurement, load voltage measurement, infrared remote control detection, etc
【Features】- The volt meter tester has a clear dial, accurate calibration, clear measurement results, and high efficiency; voltage and current testing, voltage and current can be tested without the need for normal battery installation
【Application】 - The analog multimeter is suitable for the maintenance of various colleges and universities, mechanical maintenance, communication, electric power, and circuit equipment
【Noted】 - It is strictly forbidden to test the voltage of the multimeter in the DC current. Since all multimeter current files in the instrumentation industry cannot carry voltage, this operation will cause the consequences of burning the circuit board
