multimeter for dummies

Dummies (mirroring). Example 1: A local variable in a closure is a reference rather than a copy Copy Code code as follows: function say667 () { Local variable which ends up within closure var num = 666; var sayalert = function () {alert (num);} num++; return sayalert; } var Sayalert = say667 (); Sayalert () So the execution result should pop up 667 instead of 666. Example 2: Multiple functions bind to the

the efforts made by EJB specification organizations are obvious to make EJB development easier. As they say, everything is going to be easy, but it's not easy to do that. 50 annotation tags are currently defined (and several will be published in the next draft), each with its own default rules and other actions. Of course, I really don't want EJB3.0 to turn into a EJB2.1 "EJB 3.0 = EJB 2.1 for Dummies" (hopefully this equation will not be established

the interface, features, tools, and skills you use. This is in fact dependent on your application and the environment. Using our suggested criteria, you can find the answer to the question.

default, sort by the system CPU utilization, or you can simply click on the item by mouse to change the sort method.Customizing a work sheetGuide customizing to create a work sheet shown in 14-71. Select File-> New, 14-52. Enter the title and the number of rows, that is, the maximum number of monitoring windows, here is four. 14-6Note: Minimum 2 second update interval3. Now simply drag the sensor from the left CE to the right CE window. The display can be selected as–signal Plotter. Displays on

How to open an offline Web site Using the Teleport Ultra software, you can create a new project file, and then open the appropriate Web site using offline mode. Step 1: Double-click the Teleport Ultra program icon on the desktop, open the Program main window day, click the File New Project Wizard command, as shown in the following illustration. (Universal meter and Multimeter use method http://www.woaidiannao.com/html/xwzx/6599.html) S

We first use a multimeter to measure the USB four lines (red +5v white data-data-green data-data-lacquer line) multimeter Red table pen to the ground black pen measurement (white line and Lu Liling line. The resistance of 50 euro, the two lines are from the South bridge out, if the resistance changes too large can be judged is the South bridge problem. Description USB module burned inside the South bridge

following several. Treatment: For the following reasons, exclude each. Requires you to be familiar with digital circuit analog circuit, will use multimeter, and sometimes need to use the debug card to check the fault. (1) CPU-related issues CPU does not have power: Use the multimeter to test the three (or one) field tube around the CPU and three (or one) rectifier diode, check the CPU is damaged. CPU s

Offline Live detection Under normal circumstances, in standby state of ps-on and Pw-ok two power signals, one is high, the other is low level, plug 9 feet only output +5VSB voltage, as long as the meter to measure the voltage to the parameter value, you can determine the result of the problem. Artificial Wake power supply detection Use a thin wire (such as a paper clip, fine copper wire, wire or tweezers) to ps-on the 14 feet of the ATX plug (the only Green Line) and the 3rd on the other end.

pure water, the experimental test found that tap water also meet the requirements, of course, the fear of video card problems friends can buy a few bottles of pure water to clean. First let's look at how to use tap water to clean the video card: In order to dispel everyone's concern, we first have to measure whether the electric conductivity of tap water, here need to use a multimeter, mainly using resistance to test the resistance of the water, th

into general instruments, such as oscilloscopes, multimeter and other instruments, professional strong special instruments, such as old Xie Digital TV, this professional field will have a lot of special instruments, such as SFU, VM700, TG39 and so on. by function: Lao Xie The instrument is also divided into two categories, output class (signal source) and input class (measuring instrument). In the back of the content, Lao Xie will list some

In order to search the LCD display in use of the fault, you can use the pointer-type multimeter rx10kω resistor file for tracing. This is a high resistance file, you can check the impact of the display of a variety of pass and break. And because it has 9~15v DC voltage, it can drive the LCD display, Judging whether the measuring device is normal from the display state. But since the multimeter outputs a DC

maintenance methods have advantages and limitations, often used in combination. 1. Cleaning law The brush can be brushed lightly to the dust on the motherboard, in addition, some cards on the motherboard, chip using the form of pins, often because of the oxidation of the pins and poor contact. Use eraser to surface oxidation layer, reseat. 2. The Observation Act Repeatedly look at the repair of the board, to see whether the plugs, sockets are skewed, resistors, capacitance pins are collidin

Some time ago, Ubuntu had a problem. I re-installed Version 10.10, which is different from the previous advantages and disadvantages. I will not repeat it here. I will try again later on 11.04release. Now I will briefly introduce the installation steps: 1. Install Ubuntu. The steps are relatively simple. I am not a professional programmer engaged in network clusters, but will simply install them with dummies. There is just a-year-old Chinese version o

Use vi in Linux to improve work efficiency-general Linux technology-Linux technology and application information. The following is a detailed description. The first time I used vi, I felt that it was not easy to use. Soon I replaced vi's work on Linux with gedit. But now, we finally understand the power of vi. Why did it become a standard editor for Unix and Linux 40 years ago, and its position remains unchanged until now? The answer is not required. We feel that vi is not easy to use because it

The power protection and hard disk protection functions of Thinkpad are quite good, which can ensure the stability of computer business applications. This function can also be installed in Ubuntu, but it is more complicated than the installation method of dummies in Windows, however, it is still quite a fool to execute the following command $ sudoaptitudeinstalltp-smapi-source $ sudomodule-assistantgettp-smapi-source $ sudomodule The power protection

humiliation. A man who can withstand loneliness never gets lonely, but his patience is for a better outbreak.To those who say we are dummies, say "I am dummies", so that they are at a loss! Don't argue with those who accuse us for no reason, because this will only make you angry. It is better to tolerate others than to hurt others. tolerance is the best panacea for treating others' wounds. 7. Maintain a go

wisdom in life. At work, it is a loss to do more work or do more work for others. If the leader asks you to work overtime and catch up with the task, don't think you have suffered a big loss. Instead, you should be glad that the leader only calls you but does notOther people trust you and appreciate you. A disadvantage is a contribution. The more you contribute, the more you get. Willing to work overtime is such a kind of disadvantage. 　　Willing to give up and give it to others; people who lear
