Here we talk about what are the advantages of upgrading the universal testing machine, why should the revamping, the universal testing machine upgrade can realize automatic control computer of universal testing machine testing process, but also can be manually controlled. A,universal testing machine can display three kinds of test curve of force displacement curve,force: -- -- -- time curve, displacement time curve; two, the machine measurement, control system adopts computer bus plug-in design. The whole system has the automatic zero adjustment, automatic calibration, continuous global measurement of unclassified, during the test no zero drift, stepless speed regulation and other functions; three, can be displacementrate control, and can make the displacement; four, in the process of test control speed and control function can be switched to each other; five, can be tested force, rate control, and cankeep the test force. In general is to upgrade the testing machine after the transformation ofthe use of more convenient, more powerful, more able to meet the needs of users.

這里我們講一下對(duì)萬能試驗(yàn)機(jī)升級(jí)改造后有什么好處，為什么要對(duì)其進(jìn)行改造，　對(duì)萬能試驗(yàn)機(jī)升級(jí)改造可實(shí)現(xiàn)計(jì)算機(jī)對(duì)萬能試驗(yàn)機(jī)試驗(yàn)過程的自動(dòng)控制，還可進(jìn)行手動(dòng)控制。一、萬能試驗(yàn)機(jī)可切換顯示三種試驗(yàn)曲線：力――位移曲線、力――時(shí)間曲線、位移――時(shí)間曲線；二、該機(jī)測(cè)量、控制系統(tǒng)采用計(jì)算機(jī)總線插卡式設(shè)計(jì)。整個(gè)系統(tǒng)具有自動(dòng)調(diào)零、自動(dòng)標(biāo)定、連續(xù)全程測(cè)量不分檔、試驗(yàn)過程中無零點(diǎn)漂移、無級(jí)調(diào)速等功能；三、可進(jìn)行位移速率控制，并可進(jìn)行位移保持；四、在試驗(yàn)過程中各種控制速度及控制功能均可互相切換；五、可進(jìn)行試驗(yàn)力等速率控制，并可進(jìn)行試驗(yàn)力保持。總的來說就是升級(jí)改造以后的試驗(yàn)機(jī)使用更方便，功能更強(qiáng)大，更能滿足用戶的需求。
