LJD-B型介电常数介质损耗测试仪厂家

LJD-B type dielectric constant and dielectric loss tester

一、概述：

First, an overview:

LJD-B型介电常数介质损耗测试仪厂家是我公司研制生产的产品，自该产品实现销售后，我公司工程师就一直持续不断对产品改进升级；介电常数介质损耗测试仪厂家特别是在软件上不断地加以完善，改进了早期产品存在的不足之处，提高了测试精度，并增加新的功能。但近期我公司发现，一些没有研发能力的公司，盗版了我公司早期产品的软件，仿我公司的产品进行销售，给不了解情况的客户将带来损失。因为这些产品的软件存在不足之处，（如在主电容调节至80pf左右时，电容指示值会出现跳变，出现180pf左右的指示值；在介质损耗测试时，当材料的损耗较大时，介质损耗值会出现错误。）但又无法得到升级完善，产品没有新增的功能。因此请广大用户注意识别。

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.
