1、It is suggested that the meter gets on power for 15 minutes before measuring.
2、Working environment is 0～50℃，humidity below 85%RH.
3、The calibration interval for this meter is one year.
4、Please keep the meter from shaking and shocking. Don’t place the meter in the environment full of excess dust and hazard chemicals and gas.
5、If the meter is not used for long time, please get on power every 3 months, each time not less than 4 hours.
6、To be stored in the environment at 0～50℃, humidity below 60%RH, no direct sunshine. The meter should not contact with organic solvent or oil.

The first alarm value setting
The second alarm mode:
It is similar to Ad1.
The first alarm hysteresis. For
example, if Ad1 is H, AL1=50,HY1=5,
when measuring value≥50(AL1), alarm
is active; when it is≤45(AL1-HY1),
alarm is not active.
The second alarm value setting:
It is similar to AL1
Current Transforming: it is only for
5A range or 75mV spliter current input.
If its value is set as the the ratio of external
CT or spliter, the actual range should be CT*5.
For other situation, CT is set as 1.

Communic:ation baud rate:
4.8kbps、9.6kbps for option.
Add：Meter communication address
Analog output low limit setting:
when measured value = rL set value,
the corresponding analogue output is 4mA
Analog output high limit setting:
when measured value = rH set value,
the corresponding analogue output is 20mA
VIII. Communication
This meter using Modbus RTU communication protocol, and it can run RS485 half-duplex communication. Read function code is 0x03, write function
code is 0x10, 16-bit CRC checking is applied. The meter don’t feedback error message. The communication data type is 32 bit integer data, true code stands
for positive number, complemental code stands for negative number, data rate is 0.001；for example, if the meter data received by host is 5000, then meter
data * rate = original data (5000*0.001=5.000). Therefore, when host writes meter, the data should multiply by rate 1000 before it is sent to the meter.
Data Frame format：
Start bit Data bit Stop bit Check bit
NO181
Handling of abnormal communication：
If there is abnormal response put the function code on the top position 1. For example: Host request the function code 0x03,and the response function
code from slave should be 0x83.
Error type code：
0x02---Data location error：the request data location from host computer exceeds the range of the meter.
0x03---Data value error：the data value sent by host computer exceeds the data range of the meter.
CRC check error, function code error, don’t return value.

1. Read Multiple Registers
For example: The host computer read AL1（1st alarm value 5.0）
Address code of AL1 is 0x0000，32bit（4 byte），seizes 2 data registers; hexadecimal memory code of 5.0*1000=5000 is 0x00001388.
