Precautions

1、试验工具：专用雨量量筒 1 个、小型滴管 1 个；

2、试验前的检查：

试验前先取下不锈钢外筒检查仪器水平泡是否居中、翻斗是否翻转灵活、无卡滞现象，并检查水路是否

畅通，然后用清水对引水漏斗、翻斗进行充分润湿；

3、注水试验

用双速滴水法检验仪器测量准确度，其方法为：

用专用雨量量筒量取 10mm 的清水，通过引水漏斗以 0～4mm 雨强之间任意雨强缓缓倒入上翻斗的

引水斗内，待下翻斗最后一斗欲翻未翻时，即停止注水，然后用滴管量取定量清水，一滴一滴加入到翻斗内

直到下翻斗翻转即停止滴水，依次反复试验，记录翻斗翻转次数与耗用水量。0.2mm 翻斗翻转 50 次，耗

用水量为 9.80～9.90mm，则可认定仪器翻斗倾角基点正当倒水量＜9.80mm，说明翻斗倾斜角度过小，应

适当降低调节螺钉高度；一般讲，调节螺钉转一圈，能使精度改变 2～3%。

注：本方法只作为现场应急校准仪器误差用。精确校准仪器误差必须按照国家标准 GB/T11832-2002《翻

斗雨量计》的要求在雨强试验台上进行校准或将仪器返回厂家校准。

3 read and modify device address

(1) Read or query device address

If you don't know the current device address and there is only one device on the bus, you can use the

command FA 03 00 64 00 02 90 5F Query device address.

Device ID

FA is 250 for the general address. When you don't know the address, you can use 250 to get the real

device address, 00 64 is the device model register.

For the correct query command, the device will respond, for example the response data is: 01 03 02

07 12 3A 79, the format of which is as shown in the following table:

Device ID

Function id

Start Address

Model Code

CRC16

55 3C 00 01

3A 79

Response should be in the data, the first byte 01 indicates that the real address of the current device is,

55 3C converted to decimal 20182 indicates that the current device main model is 21820, the last two bytes

00 01 Indicates that the device has a status quantity.

(2)Change device address

For example, if the current device address is 1, we want to change to 02, the command is:01 06 00 66

00 02 E8 14 .

After the change is successful, the device will return information: 02 06 00 66 00 02 E8 27 , its format

is parsed as shown in the following table:

Device ID

Response should be in the data, after the modification is successful, the first byte is the new device

address. After the general device address is changed, it will take effect immediately. At this time, the user

needs to change the query command of the software at the same time.

4 Read and Modify Baud Rate

(1) Read baud rate

The device default factory baud rate is 9600. If you need to change it, you can change it according to

the following table and the corresponding communication protocol. For example, read the current device's

baud rate ID, the command is:01 03 00 67 00 01 35 D5 , its format is parsed as follows.

Device ID

Function id

Start Address

Data Length

CRC16

00 67

00 01

35 D5

Read the baud rate encoding of the current device. Baud rate encoding: 1 is 2400; 2 is 4800; 3 is 9600;

4 is 19200; 5 is 38400; 6 is 115200.

For the correct query command, the device will respond, for example the response data is: 01 03 02

00 03 F8 45, the format of which is as shown in the following table:

Device ID

Function id

Data Length

Rate ID

CRC16

00 03

F8 45

coded according to baud rate, 03 is 9600, ie the current device has a baud rate of 9600.

(2)Change the baud rate

For example, changing the baud rate from 9600 to 38400, ie changing the code from 3 to 5, the

command is: 01 06 00 67 00 05 F8 1601 03 00 66 00 01 64 15 .

Device ID

Function id

Start Address

Target Baud Rate

CRC16

00 66

00 01

64 15

Change the baud rate from 9600 to 38400, changing the code from 3 to 5. The new baud rate will take

effect immediately, at which point the device will lose its response and the baud rate of the device should

be queried accordingly. Modified.

5 Read Correction Value

(1) Read Correction Value

When there is an error between the data and the reference standard, we can reduce the display error

by adjusting the correction value. The correction difference can be modified to be plus or minus 1000, that

is, the value range is 0-1000 or 64535 -65535. For example, when the display value is too small, we can

correct it by adding 100. The command is: 01 03 00 6B 00 01 F5 D6 . In the command 100 is hex 0x64 If

you need to reduce, you can set a negative value, such as -100, corresponding to the hexadecimal value of

FF 9C, which is calculated as 100-65535=65435, and then converted to hexadecimal to 0x FF 9C. The

correction value starts from 00 6B. We take the first parameter as an example. The correction value is read

and modified in the same way for multiple parameters.

00 6B

For the correct query command, the device will respond, for example the response data is: 01 03 02

00 64 B9 AF, the format of which is as shown in the following table:

Device ID

Function id

Data Length

Data value

CRC16

00 64

B9 AF

In the response data, the first byte 01 indicates the real address of the current device, and 00 6B is the

first state quantity correction value register. If the device has multiple parameters, other parameters

operate in this way. The same, the general temperature, humidity have this parameter, the light generally

does not have this item.

(2)Change correction value

For example, the current state quantity is too small, we want to add 1 to its true value, and the current

SD7001 Us er Manual http://www.sonbus.com/

value plus 100 correction operation command is:01 06 00 6B 00 64 F9 FD .

After the operation is successful, the device will return information: 01 06 00 6B 00 64 F9 FD, the

parameters take effect immediately after successful change.
