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。

WT-210使用过程常遇到的问题解答
1. 1. 功率往上调,值会变化但是往下调时却没有变化,还是维持在高的电 压时的数据?
2.
AN: 按SETUP进Pnlrse项,选择YES后Enter进行数据初始化设置. 如下:
1. 2. 开机时电流和功率都没法读取,只显示 - -OL- 或- -OF- ?
选择SETUP键,按向上或向下,选到AVG,点击ENTER进入选项进行选择
(ON/OFF/TYPE),选择ON则显示屏底下的整AV理Gpp指t 示灯会亮绿灯.

测试平均功率功能
关于求平均值功能
求平均值功能对测量的值执行平均计算或平均变化计算.当电源或负载引起 测试数值在较大的范围内变动,无法平稳.或者输入信号是低频信号时, 常应用 到求平均值功能,使得所测得值容易读取.测试的项目包括:电压、电流和功程太小。需要按VOLTAGE或CURRENT进行
重新设置量程,一般EE或Power工程师借过去debug或分析回路功率时会选择比精确
的量程,故会将量程设得很小。
1. 3. 电流或电压的值很小，只有0.003W左右（理论上应是0.1W左右）?
2.
AN:说明AVG平均电压功能被开启，所测的值是平均值。解决的方法是进
SETUP的AVG项，选择off。功率计面板上的AVG项绿灯就会熄灭，此时就是我们
需要测试的峰值数据。（备注：这项测试平均值，每次测试前均要确认一下是否被开启，以
免测试错误。）
