深圳前方电子科技原创作品

请不要用市场上劣质抄板跟仿制品的价格跟我们的原创做比较

1、电压表的价格在于精度，请不要单纯拿价格来做比较

2、本电压表可以测量正负电压，这一点是一般电压表所不具备的

测量范围：DC可以测量正负电压2.0000V、20.000V、200.00V。

供电电压：DC 4.5-5.5V。

PCB板采用以下：

1、采用晶振提供精准的125KHZ的时钟信号，重复采集使用更加稳定。

2、提供单线的数据通信接口，连接单片机更加方便。

成品采用安捷伦型号34401A的6位半万能表校准

精度达到正负1个字

使用原装TI ICL7135主控芯片精度达到4位半

 

目前市面上四位半的表头误差比较大 （经过测试一般的表头达到10个字，好点的也都在6个字左右的范围）

有图有真相

以下是本店用安捷伦“型号E3610A”电源跟安捷伦6位半万能表进行的实际测量测试图。
