The difference between programmer and tester:
The main function of a programmer is programming, not device testing.,Device testing is only an additional function,Its logical state reads are allio,Can't be treated differently74HCSeries and74LSseries,And it's indistinguishableCD4000Series andHEF4000Differentiation of series..Anyone with a little electronic knowledge knows it.74hcSeries and74lsThe series adopts different logic level standards,CD4000Series are not exactly the sameHEF4000series,for exampleCD4068、CD4078tangleHEF4068、HEF4078There are logical functional differences that cannot be replaced.,Such devices account for a certain proportion.
The main digital chips areTTLLevel standards andCOMSLevel standard,Maintenance Wizard Judges by Its Level Standard,To ensure test reliability.Programmers can only test whether their logical functions are correct or not.,The threshold cannot be tested..for example:Search with Programmer74HC00,The programmer will display only7400,It can't show which level standard it is..When the chip under test is aging、Decreased driving capacity、Programmers can't be tested at all when soft faults occur..Maintenance elves are judged by threshold,Similarly in search74HC00Will display74HC00,search74LS00Time display74LS00,Or inHCLS!Wait a minute and vice versa.
Please note that:
The tester without threshold judgment has no practical significance.,The design purpose of this machine is to serve the maintenance industry in the most reliable way of testing.,Please don't compare this machine with simple type judgement tester..Numbers inside the machine、Analog chips are used as many as possible.12slice!There's also a lot of resistance.、transistor、Inductance, etc..All for the most reliable test!

ask:What is on-load testing??
answer:Name of thought On-load test means that each output pin of the chip is loaded with a certain amount of load in the chip test.,Make it not work in no-load state,Closer to the working state of the chip in the actual circuit.The significance of load testing versus no-load testing lies in the ability to test for reduced drive capability.、Normal function but aging、Soft Fault Chips such as Weak Breakdown.Programmers generally use no-load testing,On-load testing is generally used in IC testers.,Large-scale tester uses multi-load variable impedance measurement with higher accuracy..Fixed Load Testing,The effect is inferior to that of mainframe, better than no-load test..
ask:What is the significance of threshold testing??
answer:Functional testing is the most basic test When the chip is seriously damaged, such as breakdown、Open circuit, etc.,Only functional testing is needed to identify it..For chip aging、The significance of driving force drop threshold test is highlighted..In the following schematic diagram, in a logic chipvt4andvt5The output level is not standard due to the decrease of beta value after aging.,Actual circuit boards may behave as normal or abnormal at times or disappear despite temperature changes..Let's use an example to verify it.:Use one74Series chips string a resistor to one of their output pins,Decreasing Driving Force of Analog Chip Aging,Programmers in Video for Market Price3000A Multivariate Brand of Domestic Programmer.Visible Programmers Can't Identify Aging Devices,Nor can we distinguish between types,And maintenance elves can be easily identified..(Please don't misunderstand and and unintentionally slander any brand programmers,The same goes for other brand programmers,The reason is that different hardware structures are designed for different purposes..http://v.youku.com/v_show/id_XMzQ5NzkxMTc2.html)(Copy this link to the address bar)
ask:Is there a cyclic test??
answer:searchUnder the directory is1+11Secondary test,Other directories are direct12Secondary test,Not next timeenterKey execution12Secondary test,If one test fails, the chip is considered to be a fault chip..
ask:Is it possible to upgrade the database??
answer:Yes?.Upgrading requires one232turnTTLDownload module.Need friends can take this link.http://item.taobao.com/item.htm?id=10913477081
Brief Introduction of Working Principle:
Maintenance Wizard Adoption2section5Battery No.,Low Power Consumption and Easy Purchase.Pressenterkey2Boot up in seconds or more.Automatically perform self-check after boot-up,The battery voltage is detected and displayed on the screen after the self-test passes.,(06Type V shows the system voltage.)Replace the battery when the power is too low,To ensure the accuracy of measurement.If there is no alarm, the measurement can be started..This machineADby10positionAD,Yes5vThe theoretical resolution of the voltage is0.0048v.It is inappropriate to measure high power thyristor by using battery power supply..Voltage stabilization value of regulator should be based on actual measurement.,You can't just look at nominal values..The default directory issearchCatalog.
