Resistor in daily life is generally directly called resistor, is a current limiting element, erni electronics is one of them, in order to be able to let you have a good understanding and use erni electronics, we now tell you about the inspection work before the use of erni electronics, I hope to be of specific help to you.

Before using erni electronics, check whether the appearance is damaged, whether the lead is rusty, and whether the end cap is loose. Then use a multimeter to check whether the resistance value is consistent with the nominal resistance value. Before measurement, the appropriate resistance level should be selected and the resistor level should be zeroed. When measuring, hold the two pens of the multimeter in one hand, hold the middle of the erni electronics in the other hand, and contact the two leading ends of the erni electronics with the two pens to measure its resistance. For the smaller erni electronics, it can be placed on a table and measured directly with a stylus. After retest, erni electronics that does not conform to the mark, generally do not choose.

If you are interested in our erni electronics, you can leave us a message directly, or contact our customer service staff, we will receive your information, will contact you in time. Thank you for your support and watching, we will regularly for you to check, welcome to cooperate with us.
