In order to use other interface chips smoothly and achieve the expected results, it is necessary to check them before they are formally put into use. In order for users to have a better understanding of them, relevant technical personnel have introduced the check contents as follows:
According to the introduction can understand
1, before use, to check its quality
other interface chips Before use, 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 the measurement, the appropriate resistance level should be selected and the resistance level should be zeroed.
When measuring, hold the two pens of the multimeter in one hand (the same as holding chopsticks), hold the middle of the resistor in the other hand, and contact the two leading ends of the resistor with the two pens to measure its resistance value. For smaller resistors, they can be placed on a table and measured directly with a pen. After retest, resistors that do not conform to the mark are generally not selected.
2, the power of the chip resistance is less than the general resistance, the use of different power chip resistance, to leave a margin.
Only after we do a good job of checking the work before its use, can it be used smoothly, so as to meet the needs of the majority of users.
