2仪表主要功能 2.1电量分时计量本仪表有两种配置：TH 及TF 型（由模式字1的b6设置）。

TH 型为双方向电能表，它可以计量正、反向有功，4象限无功以及 A B 、C 各元件有功、无功电量。

TF 型为单方向电能表，它可以计量正向有功，4象限无功以及 A B 、C 各元件有功、无功电量，反向有功计量精度不作保证，仅供参考。

TH 型和TF 型电能表都能计量 2种组合的无功电量，2种组合的无功电量可由 4个象限的无功电量任意组合（通过无功组合模式字设置）。

各种总电量均可以按最大 8种费率时段进行分时计量（ A B 、C各元件的电量不分时计量）。

本表计可设置主副两套时段。

电表是否进行主副两套时段切换，受电表模式字 3的b6位控制。

每套时段最大8费率。

每套时段可设置最大 10个年时区切换数，最大 8个日时段表，每天最大 14时段切换。

每套时段可设置 90个公共假日，可设置周休日时段。

百年日历、时间，闰年自动切换。

注意，如果时段表中某一时段的费率号大于费率数时（设置错误），此时段的电量计入费率1。

电量显示小数位数设为 2时：有功电量，最大累计电量为799999.99kW.h 。

对于无功电量，最大累计电量为土799999.99kvar.h 。

电量为负值可能发生在组合无功电量中，由于考虑到电量可能为负，数据设计为带符号，正数范围 0.00 — 799999.99，负数范围：0.00 ―― 799999.99。

反向有功电量是否计入正向有功电量由模式字2的b2确定。

2.2 最大需量分时计量TH型电表可计算正、反向有功、输入无功（I +n）及输出无功（川+W）最大需量及其出现时间（年月日时分）；TF型电表可计算正向有功、输入无功（I +n）及输出无功（川+W）最大需量及其出现时间（年月日时分）。

两种配置均可以计量8种费率的最大需量及其发生时间。

最大需量的积分周期和滑差步进时间可选择，滑差时间只能设置为1、2、3、5、10分钟，需量周期与滑差时间的设置必须满足下述关系：1 < （需量周期十滑差时间）< 15,且需量周期能被滑差时间整除。

需量与时钟同步，且掉电时间小于需量周期时掉电期间需量连续（有停电抄表电池时），掉电期间需量是否连续，由模式字3的b3控制，b3 =1 :连续，b3=0:不连续。

2.3 跨月结算本表存储了上1月到上13月的历史数据（包含正反向有功、组合无功1和组合无功2、四象限无功的总电量以及分时电量，正反向有功、输入输出无功的最大需量及其出现时间，各元件有功、无功电量）跨月结算时，先把本月的电量、最大需量及其发生时间存入上月，再把本月的最大需量及其发生时间清零，计算需量的累加单元清零，需量重新开始计算。

如果电表掉电跨过结算日、时，上电后电表将进行跨月结算，跨过几个月，结算几个月。

但跨过13个月后，电表不结算。

2.4 测量功能本仪表测量总及A、B、C各相的电压、电流、视在功率、有功功率、无功功率、功率因数及电网频率，并且显示功率的方向。

两个RS485口通信地址互相独立，波特率可在 1200bps 、2400 bps 、4800 bps 、9600bps 间改变，吸附式红外波特率固定为 1200bps ，远红外口波特率固定为1200bps 。

吸附式红外和远红外通信地址与第一路 RS485相同。

2.6.1 .第一路 RS485为主RS485 口，可进行读写操作。

2.6.2 .第二路RS485一般为读操作，通过程序在第一路 RS485 口或红外口设置后也可以进行写操作。

吸附式红外与远红外口可进行读写操作。

停电后，停电抄表电池给电表供电，电表运行在睡眠状态。

电表在睡眠状态下被唤醒后是否可进行远红外抄读，受模式字控制（模式字2的b1）。

2.6.3.缩位抄表在单表通信时，无论表的通信地址是什么，只要输入12个“A ”作为通信地址就行了。

在多表通信时，取通信地址后 3位，前面全用 A 替换即可。

如：123456789123，只要输入 AAAAAAAAA12即可。

但在设置参数时最少保留3位通信地址。

2.6.4 .广播校时有不带密码的广播校时和带密码的广播校时 2种方式，由模式字1的b4决定。

所有电网类事件记录，在遇到掉电时，都无条件的结束当次事件。

对于所有电网类事件记录，如果下面两个条件同时满足，将已经发生的电网事件记录结束，对于没有发生的事件记录不再判断；如果有任意一条不满足，则正常判断和记录电网事件记录。
