Gently wipe the platinum ring of the electrode with a cotton swab, then rinse with tap water, and the cleaning is complete. If the platinum ring of the electrode has formed an oxide film, please use toothpaste or 1000-grit fine sandpaper to properly polish the sensing surface, and then clean it with tap water. The platinum ring is connected to the glass, so please handle it carefully when polishing. 1009 -The electrode has a service life of about one year, and a new electrode should be replaced in time after aging. 1010 -* Before the cable plug and the device plug are locked, do not put the plug part into water. 1011 - 1012 - 1013 - 1014 -== 6.6 RS485 Commands == 1015 - 1016 -RS485 signal 1017 -Standard Modbus-RTU protocol, baud rate: 9600; check bit: none; data bit: 8; stop bit: 1 1018 - 1019 - 1020 -== 6.7 Query data == 1021 - 1022 -Example 1: Read the current residual chlorine concentration of the device with address 01 1023 - 1024 -(% border="1" cellspacing="3" style="background-color:#f2f2f2; width:534.333px" %) 1025 -|=(% style="width: 42px;background-color:#4F81BD;color:white" %)Address|=(% style="width: 53px;background-color:#4F81BD;color:white" %)Function code|=(% style="width: 74px; background-color: rgb(79, 129, 189); color: white;" %)Register Address|=(% style="width: 94px; background-color: rgb(79, 129, 189); color: white;" %)Register length|=(% style="width: 72px; background-color: rgb(79, 129, 189); color: white;" %)CRC16 low|=(% style="width: 77px; background-color: rgb(79, 129, 189); color: white;" %)CRC16 high 1026 -|(% style="width:99px" %)0X01|(% style="width:112px" %)0X03|(% style="width:74px" %)0X00 0X00|(% style="width:94px" %)0X00 0X01|(% style="width:72px" %)((( 1027 -0X84 1028 -)))|(% style="width:77px" %)0X0A 1029 - 1030 -**response:** 1031 - 1032 -(% border="1" cellspacing="3" style="background-color:#f2f2f2; width:534.333px" %) 1033 -|=(% style="width: 42px;background-color:#4F81BD;color:white" %)Address|=(% style="width: 83px; background-color: rgb(79, 129, 189); color: white;" %)Function code|=(% style="width: 110px; background-color: rgb(79, 129, 189); color: white;" %)Valid Bytes|=(% style="width: 94px; background-color: rgb(79, 129, 189); color: white;" %)Register contents|=(% style="width: 72px; background-color: rgb(79, 129, 189); color: white;" %)CRC16 low|=(% style="width: 77px; background-color: rgb(79, 129, 189); color: white;" %)CRC16 high 1034 -|(% style="width:99px" %)0X01|(% style="width:83px" %)0X03|(% style="width:110px" %)0X02|(% style="width:94px" %)0X03 0X16|(% style="width:72px" %)((( 1035 -0X39 1036 -)))|(% style="width:77px" %)0X7A 1037 - 1038 -Calculation of residual chlorine concentration: 316H (hexadecimal) = 790 => residual chlorine = 7.90 1039 - 1040 - 1041 -Example 2: Set the deviation value for the current residual chlorine value of the device with address 01 to correct the value and send the frame: (If the current residual gas value output by the device is 7.90, the value needs to be corrected to 8.00, the difference is 8.00-7.90-0.100.1*100=10=>41200000 (floating point number), write 41200000 to the contents of the two registers) 1042 - 1043 -(% border="1" cellspacing="3" style="background-color:#f2f2f2; width:518px" %) 1044 -|=(% style="width: 80.75px;background-color:#4F81BD;color:white" %)Original address|=(% style="width: 64.75px;background-color:#4F81BD;color:white" %)Function code|=(% style="width: 64.75px;background-color:#4F81BD;color:white" %)Register address|=(% style="width: 64.75px;background-color:#4F81BD;color:white" %)Register number|=(% style="width: 64.75px;background-color:#4F81BD;color:white" %)Byte number|=(% style="width: 64.75px; background-color: rgb(79, 129, 189); color: white;" %)Register content|=(% style="width: 54.75px;background-color:#4F81BD;color:white" %)CRC16 low|=(% style="width: 58.75px;background-color:#4F81BD;color:white" %)CRC16 high 1045 -|(% style="width:99px" %)0X01|(% style="width:112px" %)0X10|(% style="width:135px" %)0X01 0X12|(% style="width:126px" %)0X00 0X02|(% style="width:85px" %)0X04|(% style="width:1px" %)0X4120 0X0000|(% style="width:1px" %)0X08|(% style="width:1px" %)0X1A 1046 - 1047 -**response:** 1048 - 1049 -(% border="1" cellspacing="3" style="background-color:#f2f2f2; width:534.333px" %) 1050 -|=(% style="width: 42px;background-color:#4F81BD;color:white" %)Address|=(% style="width: 83px; background-color: rgb(79, 129, 189); color: white;" %)Function code|=(% style="width: 110px; background-color: rgb(79, 129, 189); color: white;" %)Register address|=(% style="width: 94px; background-color: rgb(79, 129, 189); color: white;" %)Register number|=(% style="width: 72px; background-color: rgb(79, 129, 189); color: white;" %)CRC16 low|=(% style="width: 77px; background-color: rgb(79, 129, 189); color: white;" %)CRC16 high 1051 -|(% style="width:99px" %)0X01|(% style="width:83px" %)0X10|(% style="width:110px" %)0X01 0X12|(% style="width:94px" %)0X00 0X02|(% style="width:72px" %)((( 1052 -0XE5 1053 -)))|(% style="width:77px" %)0X0D 1054 - 1055 - 1056 - 1057 -= 7.
