直流电能表使用说明
DC Energy Meter Operating Instructions
一、概述General
直流电能表根据我国对电力设备运行和计算机智能化监控要求而设计,能够直接测量显示系统的用电量
和历史用电量,并带有RS485或RS232接口,与微机进行数据交换。适合蓄电池,太阳能电池板等直流信
号设备电量测量和电能计量使用,亦可用于工矿企业,民用建筑,楼宇自动化等现代供配直流电系统。
DCM3366系列产品有多种不同型号,产品功能众多,可满足目前国内外不同场合的特殊要求。
可测量如下参数:
1路电压,1路独立电流、功率。1路独立直流电能及总电能、1路独立的过去12月每月独立累计电能、1路
总的过去12月每月独立累计电能、1路独立的过去360天每天独立累计电能、1路总的过去360天每天独立
累计电能、1路独立最大功率、最小功率及1路总的最大功率、最小功率等大量历史电量。
DC energy meter is able to directly measure the display system power consumption and
electricity history. The RS485/RS232 port can exchange data with the microcomputer. It is
suitable to be used for batteries, solar panels power DC signal measurement and energy
metering equipment. Be used for industrial and mining enterprises, civil construction,
building automation and other modern DC system for distribution.DCM3366 series provides
many different types of products which can meet domestic and international market specific
requirements.
Measure the following parameters:
1-way voltage, 1-way independent current, power,1-way independent direct current and total
power, 1-way independent and total cumulative energy of each day in the past 12 months
monthly, 1-way independent and total cumulative energy of each day in the past 360 days. 1
-way independent and total max power, min. power other max history power quantity.

三、显示操作Display Operating
每次上电显示为日期画面,按 键依次显示为:功率、电流、电压、电能、时间、日期;按 键依次显示为:时间、电能、电压、电流、功率、日期。若没有按键操作,超过设定的延时模式切换时间则进入自动循环显示状态(轮显时间,出厂默认值:60s),LCD显示数据屏用户可以根据要求自己设定。
The screen shows the date when the power is on. Press Power to display: power, current, voltage, energy, time, date; Press key to display: time, energy, voltage, current, power, date. If there is no button operation and preset value is overtime, it will enter the cycle display statues (default value: 60s), the display data on the LCD can be requested by the customers.
