华知科三相智能电参数测量仪说明书电参数测试仪使用方法：先将仪表的电源线按标准接法接到电源上。

将负载用电源接到固定的端子上。

按下仪表电源开关，接通仪表电源。

接通负载电源，并使负载通电，此时仪表应显示被测负载的各被测参数值。

如测量参数超出量程，则在相应的超量程参数窗口显示“OVER”，此时应立即终止测量，并切断负载电源，以免损坏仪表。

电参数综合测量仪，主要用来测定相关仪器仪表的电力参数，如电压、电流、电功率等。

电参数综合测量仪主要有数字电力参数测量仪、单相电力参数测量仪以及三相电力参数测量仪等等。

其中数字电力参数测量仪采用表贴技术，体积更小、质量更稳定，有丰富的接口功能及测量功能，能满足实验室工频产品检测要求。

电测量仪器是将被测电量或电参数与电学标准进行比较或提供准确比例的测量仪器。

科学研究、量值传递和工业测试中所用大量较量仪器（比较测量仪器的简称）都属于电测量仪器。

其用途广泛，在计量测试领域占有重要地位。

电测量仪器主要利用比例技术实现测量。

对于直流电，是利用同一电流在两电阻上产生的电压所形成的电压比例，或利用同一电压下两电阻的电流比例，然后结合标准器实现测量未知量。

提供比例的装置犹如天平，标准器则相当于砝码。

根据这一类比制成的较量仪器有直流电桥、直流电位差计等。

对于交流电，测量原理与直流电基本相同，只是电阻由阻抗代替。

因此，一般情况下比例是复数；实数比例或虚数比例只是其特例。

此外，还可利用两个有磁耦合的线圈得到与匝数成正比的电压实数比例，或与匝数成反比的电流实数比例。

根据这些原理制成的较量仪器有经典交流电桥、感应耦合比例臂电桥、交流电位差计、感应分压器、电流比较仪、互感器等。

除了上述电测量仪器外，还有利用电子电路组成的等值电路元件以及利用数字技术制成的有源电桥和数字电桥等。

外接键盘和机器面板上的按键可以同时使用。

第二章 基本操作3.3.2注意：频率只有在标频状态下才可以调节，在市频状态下不能调节。

3.3两种状态的转换方法是：在主菜单中选择，然后按下。

4.调位相位4.1键选择三相同时调节。

4.2输入相位值后，按回车相位缓变到设定值，可以用旋钮对相位做步进调节，按下旋钮可以改变步进值，当前步进值显示在状态信息栏上。

4.3也可以用快捷方式调节相位，方法是按下COS，然后从菜单中选择所需的功率因数点，则相位直接调节到相应点上。

5. 调节对比度1．液晶的显示明暗变化因环境温度而改变，必要时应调节对比度使显示清晰。

2．在主菜单中选择，再按，然后转动旋钮调节，调到一个合适的对比度之后，按下旋钮或按或结束调节。

6.谐波设置（以电压为例，电流相同）1．在主菜单中选择，再按。

2．按箭头键或转动旋钮，移动光标到某一次谐波的相位或幅度上，输入数值后按回车确认。

347.*”号表示启用谐波，8888，再按下。

其在小圈数校验时会有较大变差，因此应使用滤波功能，□设置方法：输入滤波圈数（范围2~20），再按，此时菜单上显示一个“*”号，表示已启用滤波功能。

□如果不需要滤波功能，则输入1，再按。

-4--5-3.1 起动试验1. 在检表菜单中，按起动试验，电流会升至50%Ib ，开始自动找黑点，找到黑点后，自动调节到设定的起动电流，状态信息栏上显示起动电流的大小和计时时间；再次遇到黑点后停止计时。

该系列仪表可广泛应用于控制系统、SCADA系统和能源管理系统、变电站自动化、配电网自动化、小区电力监控、工业自动化、智能建筑、智能型配电盘、开关柜中；有安装方便、接线简单、维护方便、工程量小、现场可编程设置输入参数的特点。

警告 如果不按说明书操作会发生意外，而且会导致产品毁坏。
