100.0A. After the corresponding ratio is set, the meter
will display the corresponding data.Users are not
allowed to change the input size of the signal by
themselves. If the user has set a 100A/75mV meter
and found the voltage transmitter at the work site to be
500A/75mV, the current transformation ratio is
changed from 100 to 500, but it must be confirmed
that the output signal of the DC transmitter cannot be
changed, in this case it is 75mV .

”。
Modbus-RTU protocol: The default is
"9600,8,n,1".
6.3.3 报警功能及参数设置 Alarm function and parameter setting
正常测量时，有报警产生，并且会在继电器输
出上产生一个输出（需加配，继电器常开结点闭
合），对应 DO 显示位相应显示。
报警状态可通讯读取，参量地址见通讯参量地
址表
报警功能默认为关闭状态，除非客户要求。
当输入信号为零时，仪表可通过设置关闭或打
开低报警功能。
In the normal measurement, an alarm is
generated and an output is generated on the relay
output (need to be added, normally open relay contact
is closed), the corresponding display of the DO
displays.
The alarm status can be read by communication.
See the communication parameter address table for
the parameter address.
The alarm function is turned off by default unless
requested by the customer.
When the input signal is zero, the meter can be
set to turn off or on the low alarm function.

7.1 概述 Overview
DJSF1352-RN 仪 表 采 用 Modbus-RTU 协 议 ：
“9600，8，n，1”，其中 38400 为默认波特率，可
通过编程修改为
1200
、
2400
、
4800
、
9600
等，；
8
表示有
8
个数据位；
n
表示无奇偶校验位；
1
表示
有 1 个停止位。
The DJSF1352-RN meter uses the Modbus-RTU
protocol: “9600, 8, n, 1”, where 38400 is the default
baud rate, which can be programmed to change to
1200, 2400, 4800, 9600, etc.; 8 means there are 8 data
bits ;n indicates no parity; 1 indicates 1 stop bit.
Error detection: CRC16 (Cyclic Redundancy
Check)
DJSF1352-RN 仪表采用 DLT645 协议,支持 07、
97 版本，仪表表号默认为条形码后 12 位，详见菜

DJSF1352-RN meter adopts DLT645 protocol,
supports 07, 97 version. The meter number defaults to
12 digits after barcode. See menu settings for
details.The protocol supports reading of voltage,
current, power, forward and reverse direction and
combined energy and reading of multi-rate energy. At
the same time, the version 07 protocol also supports
programming records, reading of 10 events of time
setting, and 12 months of multi-rate energy and
demand, 3 times data instantaneous freezing and 12
times frozen data query.
