multimeter for dummies

First, the multimeter to the test diode end, with the multimeter of the Red pen to one of the transistor's pin, and the other side of the multimeter to test the remaining pins, until the following results are tested: 1, if the transistor's black form pen to connect one of the pins, and the Red Watch pen to test the other two pins are on the voltage display, then

a testing tool is introduced that is not supported by people. People should see the need to improve a specific process, and be aware that the introduction of a specific test tool may ultimately help to accomplish their work more efficiently. If an organization does not sort these three points in order, the sentence "with the test tool, dummies are still dummies" will come true. Or in other words, an organi

C-language dummies (1): nested loops-program structure, dummies Loop statement nesting a loop structure can contain another loop, called loop nesting, or multiple loops. The nested loop is a double loop. The outer loop is called an external loop, and the inner loop is called an internal loop. --------- I don't know where the basic concepts come from 　　 　　This is the first blog of the baby. I will not ask fo

When you solve a user's PC fault, do not forget to use a multimeter to test the power supply. Learn some simple and easy-to-use skills to help you eliminate the possibility of power failure. It may not seem obvious, but more than 1/4 of PC problems are related to power problems to some extent. You may think that if there is a problem with the power supply, the PC will not start up at all, and the culprit will be easily identified. But the problem is

How to use the digital Universal meter to measure the polarity of transistors and the method of NPN, PNP . First of all, say the pointer of the multimeter and the digital multimeter of the red-black pen and the internal battery connection difference;So there are some differences between the two types of tables. Next, just talk about how to use the digital measurements. Use a digital

Digital multimeter test and the pointer multimeter is different, then how to test the polarity of the transistor with a digital multimeter. First, the multimeter to the test diode end, with the multimeter of the Red pen to one of the transistor's pin, and the other side of

Currently, almost all digital multimeter use dedicated integrated circuits for A/D conversion. Table 1 lists some common number table A/D chip configurations. I. Replacement of the mode/number Converter Currently, almost all digital multimeter use dedicated integrated circuits for A/D conversion. Table 1 lists some common number table A/D chip configurations. Icl7106, icl7126, and icl7136 belong to th

Summary 2--- multimeter measures the voltage of square wave and sine waveThe voltage of the square wave measured by the multimeter is the average and the sine wave is a valid value.The reason is: the multimeter uses the integral ADC, the results are averaged. ... Why is this, check the time, then continue!!---------------------------------------------------------

Method one dials the pointer multimeter to the "rx1k" file, and the ESC is zeroed. The field effect is the same side of the word, from left to right: G (Gate), D (drain), S (source). The Black Watch pen is connected to the D-Pole, the red pen is connected to the S-pole, at this time, the multimeter hands should not move, and then swap the pen, then test, at this time, the

each pin is. The first step in the test is to determine which pin is the base pole. At this point, we take two electrodes (such as the two electrodes are 1, 2), with Avometer two pens to measure its positive and reverse resistance, observe the deflection angle of the needle, and then take 1, 32 electrodes and 2, 32 electrodes, respectively, the reverse measurement of their positive and negative resistance, to observe the angle of the needle deflection. In these three reversal measurements, ther

When a digital multimeter is used to measure the diode, the positive voltage value of the diode is measured, and the positive and reverse resistance value of the diode is measured. That is, the digital multimeter,

Fluke Networks Fluke Network) recently released a new NetTool II series online network multimeter with the NetProve diagnostic function. It diagnoses Enterprise Network and application connectivity faults four times faster than traditional methods.The newly released NetTool II series has a simple one-step NetProve test function, allowing technicians to quickly and conveniently identify the root cause of the problem regardless of their expertise.

Digital Multimeter is now a very popular electronic measurement tools, because of its ease of use and accuracy by the electronic technology staff's favorite. However, it is often said that when measuring certain components, it is not as convenient as a pointer multimeter, especially when measuring transistors. In fact, I feel a digital multimeter to measure the t

The following is the structure of the transistor and the various identification methods in the circuit diagram When the multimeter is measured against the transistor (buzzer), we first determine which foot is the B-pole. With a red pen touch any one of the feet, the black pen to contact the other two feet, if you can measure the two groups of similar and less than 1 of the number, indicating that the Red pen contact is the B pole. If the two sets o

In the book that you'll find eight complete ASP. NET applications. We're not talking trivial (mediocre) hello-world-type applications here. Instead, they're real-world applications like shopping carts and discussion (discussion) Forums (forum ). You can use any of them as-is, or modify them as you see

This article uses the popular saying "dumb camera" to create the word "dumb Ubuntu", which means automatic or semi-automatic Ubuntu. In this case, the actual level of Ubuntu is not low! Is this true? As you know, the actual users of dummies Ubuntu may not be really dummies. Recently, the Beta3 version of Ubuntu9.10 has just been released. From the perspective of it, the beautiful faces are indeed extraordin

J. Timothy King wrote a great article: Twelve benefits of writing unit tests first ). Unfortunately, what he said at the end of the article is completely superfluous. However, if you don't want to get rid of the old habit of writing code first, if you think that self-stick is more important than designing good software, Well, I am sorry for you. Using your pity on people who do not agree with you is not the most effective way to promote your claim. Let's take a look at Mr t's example. He bega
