Inside it contains neon to the high value of resistance, the resistance has the duty to limit the amount of current that will flow through the neon and the body won't be dangerous. If it is exposed to light, which is part of the power of integrated. By electricity will flow from the tip screwdriver through the neon tubes. Resistor inches sleeve body into space, stood by a neon light bulb when the pressure reaches the coordinates that Neon will light.3. Select a screwdriver try electrical power should be selected to suit the type of electrical voltage and size. 3.1 types of electricity such as DC/DC (car) Alternating current AC (used with fire coming from the spikes). 3.2, size must be sufficient voltage. Not too high or low selection pressure may be valuable screwdriver phone but do not feel that there is security light leak through much of the time such as tap screwdriver electrical home power 200-250 volts, but use a screwdriver for 80-125 volts, voltage, etc.4. be careful not to touch the bare part screwdriver touch. Should use insulated screwdrivers to only touch the tip to use. If it is not. There may be thousands of ways, must be used with duct tapes, which will help to reduce or prevent accidental short circuit occurring from the use of a screwdriver that is not careful with the.5. try general power screwdrivers for home use usually have a button on top, or as a khlip pen clip allows for power using integrated flow through the body.

" Neon lights or defective internal resistance may be unavailable (no stick) or if it is a digital display indicator may not work, so before using khaikhuang, then that should be tested. By testing with the sure knowledge that there was a fire before, such as a screwdriver to try to fire home lighting types, use the test by tease. Into the hole in the wall will have only one hole with a fire, etc.9. เวลาแหย่ ไขควงลองไฟ ต้องระมัดระวังอย่าให้ไขควงไปแตะส่วนอื่นที่เป็นขั้วไฟคนละขั้วพร้อมกัน เช่น ขั้วไฟต่างเฟส หรือ ขั้วมีไฟแตะกับขั้วดินหรือนิวทรัล เป็นต้น โดยเฉพาะอย่างยิ่งในที่แคบๆ เพราะนั่นหมายถึงการทำให้เกิดลัดวงจรและจะมีประกายไฟที่รุนแรงพุ่งเข้าสู่ใบหน้าและดวงตาจนอาจเสียโฉมหรือพิการได้ ดังนั้น ในสถานการณ์ที่มีขั้วไฟฟ้าเปิดโล่ง หรือเปลือย เช่น ตู้แผงสวิตช์ หรือเต้ารับที่เปิดฝาออก ไม่แนะนำให้ผู้ที่ไม่ใช่ช่างไฟฟ้าทำงานโดยเด็ดขาด10. ห้ามซ่อมหรือดัดแปลงไขควงลองไฟที่ชำรุดเป็นอันขาด เช่น การเปลี่ยนค่าความต้านทาน หรือต่อตรงความต้านทาน เป็นต้น11. ห้ามนำไขควงลองไฟไปใช้ทดสอบกับไฟฟ้าที่ไม่รู้ค่าแรงดัน หรือไฟฟ้าแรงดันสูง
