功率表2012  600V/20A/12KW

    本系列数字位瓦特表具有3个电压档位，3个电流档位，及9个瓦特档位，适当的解析度与较合理的价位是你较佳的选择。    
 

产品特点

．基本+/- 0.1%的准确度
．电压、电流与瓦特皆为True RMS 量测
．电压及电流具有手动或自动的换档功能，及自动换档之频率量测
．使用4 1/2位类比数位转换器为基准，提供高准确度、高解析度及高稳定度的量测
．使用3个多工的显示器，可依所需来选择，且均可选择所有的量测功能(Vrms, Arms, Vrms, PF, VA, VAR, Hz) 
．具有电压三段、电流三段及瓦特九段的输入档位选择
．自动保存关机前之设定状态，关机后自动回复原先设定
．输入电流峰值**过档位警告
