1、使用前請(qǐng)注意將筆桿、導(dǎo)線、夾子連接好，形成電路通路。
2、筆桿內(nèi)的LED有正負(fù)極之分，筆尖端作為正極，夾子接地作為負(fù)極，接反不能用于檢測(cè)電路。
3、測(cè)試電路時(shí)，請(qǐng)?jiān)?V-24V（汽車(chē)/摩托車(chē)）或36V-72V（電動(dòng)車(chē)）的電壓范圍內(nèi)使用，超過(guò)24V或72V以上電壓容易使筆內(nèi)的LED發(fā)光管燒毀或縮短測(cè)試筆的壽命。

Product Description:

1. Please note that before using the pen, wire, clip connected to form a circuit path.
2. the LED pen of positive and negative, positive tip of the pen, clip ground as a negative, reverse can  not be used in the detection circuit.
3. Test circuit used in the voltage range of 6V~24V ( car / motorcycle ) or 36V~72V ( electric vehicles ), the voltage more than 24V or 72V easy to make LED lamp burned or shorten the test pen pen life.

敬告：因?yàn)槭褂冕槧钗飳?dǎo)致受傷的危險(xiǎn)系數(shù)較高，所以請(qǐng)根據(jù)自己的使用習(xí)慣或需要改變測(cè)試筆金屬端的使用形狀。

Warning: Do not use needles lead to higher risk of injury factor. so according to their own habits need to change the use of the metal end of the test pen shape.
