WTViewerFreePlus 软件可用于监视和保存所有这些参数数据，最多可达200个。
便捷的测量功能• 最大值保持功能可以保持RMS/PEAK 电压&电流、有功功率、无功功率和视在功率的最大值。
• 线路滤波器和频率滤波器功能这些滤波器功能将为基波测量过滤掉不需要的噪声和谐波成分。
积分测量时的自动量程功能通常，当功率计在积分模式下测量功耗和待机功率时，需要将测量量程固定。
但是，如果输入电压或电流超过被选量程的最大值，测量结果将出错，并且需要以最高量程执行重复测试。
WT300E 系列可以在积分模式下快速地自动切换量程，这不但可省去上述重复测试的麻烦，还可保证积分的连续性和准确度。
该功能不但可以测量正负瓦时，还可以测量安时以及DC 电流。
峰值因数“6A ”模式在CF=6A 的情况下，电压和电流的最大额定输入变为量程的260%，最大可显示到280%。
需要进行高分辨率测量时，通过该模式可以避免频繁的电流量程变动。
指定量程间的自动量程功能自动量程功能可用于在指定量程间自动选择/切换量程。
特点与优势快速显示和数据更新率WT300E 系列拥有快速显示和最大100ms 的数据更新率，可为用户缩短测试过程的工时。
