LJD-B型介電常數(shù)介質(zhì)損耗測試儀廠家

LJD-B type dielectric constant and dielectric loss tester

一、概述：

First, an overview:

LJD-B型介電常數(shù)介質(zhì)損耗測試儀廠家是我公司研制生產(chǎn)的產(chǎn)品，自該產(chǎn)品實(shí)現(xiàn)銷售后，我公司工程師就一直持續(xù)不斷對產(chǎn)品改進(jìn)升級；介電常數(shù)介質(zhì)損耗測試儀廠家特別是在軟件上不斷地加以完善，改進(jìn)了早期產(chǎn)品存在的不足之處，提高了測試精度，并增加新的功能。但近期我公司發(fā)現(xiàn)，一些沒有研發(fā)能力的公司，盜版了我公司早期產(chǎn)品的軟件，仿我公司的產(chǎn)品進(jìn)行銷售，給不了解情況的客戶將帶來損失。因?yàn)檫@些產(chǎn)品的軟件存在不足之處，（如在主電容調(diào)節(jié)至80pf左右時(shí)，電容指示值會出現(xiàn)跳變，出現(xiàn)180pf左右的指示值；在介質(zhì)損耗測試時(shí)，當(dāng)材料的損耗較大時(shí)，介質(zhì)損耗值會出現(xiàn)錯(cuò)誤。）但又無法得到升級完善，產(chǎn)品沒有新增的功能。因此請廣大用戶注意識別。

LJD-B dielectric electric constant and dielectric loss tester is my company exclusive development and production of products, from the realization of the product sales, company engineers have been continuing to continuous product improvement and upgrade, especially in the software constantly perfected and improved the deficiencies existed in the early, to improve the accuracy of the test, and added new features. But recently we found that some no R & D capability of bad company, pirated software in my company's early products, imitation fake my company's products sales and to understand the customer will bring losses. Because of these products software shortcomings, as in the main capacitor is adjusted to about 80pf, capacitance indication value will appear to jump, value indicating 180pf about; in the dielectric loss test, when the errors will occur in the material loss is large, the dielectric loss value. But can not be upgraded and improved, the product has no new features. So please pay attention to the majority of users.
