بعدNote: If you are not a professional fan, without a certain level of technology, carefully shot, on the use of the product you explain to us a closer look, we do not know where to direct messages. See wiring method further understand the electrical test after the baby received good and then the solder, due to their own wrong line or DIY altered exclude warranty Oh!
Calibration instructions:
The module with a calibration function, do not worry about the problem of inaccurate measurements show that the normal pre-delivery will be issued after the calibration, if you find that are not allowed to display, you can use the following method of calibration.
Calibration method: Connect precise 12V (100V independent power supply for 30V) when the power is short-circuited temperature sensitive resistor for 5 seconds, the screen will black out, disconnect the power to connect the calibration Well, pay attention to 12V power supply must be accurate, otherwise calibrated also not allowed.

ضمن اینکهProduct Features:
◆ blue white, clear and beautiful; ordinary digital meter with a long period of time there will be no shortage of Dan, this product uses STN screen does not have this problem; the use of wide-angle screen STN, TN screen product on the market is not comparable, viewing angle large and very clear.
◆ screen display with voltage and current, with a MODBUS protocol functions can be used with PC, PLC communication equipment for data collection.
Product parameters:
◆ voltage: non-independent power supply can be measured 5-30V, independent power supply can be measured 0-100V (non-independent power supply module refers to the supply voltage is the voltage to be measured, independent power supply refers to the supply module and the measured voltage are separated, this time module supply voltage 5-24V, the measured voltage 0-100V)
◆ Current: 0-10A
◆ temperature: -20-100 degrees
◆ Accuracy: 1% (± 1 word, the greater the voltage and current range, accuracy reduced accordingly)
◆ supports standard Modbus RTU protocol, RS485 communication
Product Features:
◆ one voltage measurement, current measurement all the way, all the way to measure temperature (fever due to the first table, there is resistance default temperature distribution, but not welded, self-extended, can improve the measurement accuracy)
◆ voltage and temperature automatically switch display, the current separate row (display mode can be set via button Temperature: In case of power failure, press and hold the button is not loose, electricity, three seconds after release the button, you can switch back on the power mode)
◆ protocol functions can be set with device addresses 1-255, through the PC software settings;
Interface Description:
◆ left pin A, B-side for the RS485 interface for Modbus communication
◆ GND voltage below the negative, IIN with measurable current, independent power supply for the module when the VCC power supply positive, non-independent power supply for the positive test voltage, VIN independent power supply voltage is positive.
1. Press the wiring diagram connecting hardware
2. Software settings:
In the "Communication Settings" set the serial number, open the serial port.
In the "Analog capture" item set module address (default address is "1", in the case of unknown module address, you can "change the module address" item of the module address changes)
In the "Analog capture" click "acquisition" command on it.
As a "communication error" to confirm RS485 interfaces A, B whether the reverse side.
منظورتون از نحوه اتصال چیه ؟
نحوه اتصالش به کامپیوتر یا راه اندازی خود ماژول؟
اگر منظورتون نحوه اتصالش به کامپیوتره که چون پروتکل ارتباطیش RS485 هست میتونید که تبدیل 485 به usb مطابق عکس بهش وصل کنید و از نرم افزار استفاده کنید:
اگه به عکسی که گذاشتم دقت کنید متوجه می شید که حتی ترتیب A و B رو هم معلوم کرده
اگر هم منظورتون نحوه اتصالات مربوط به پاور و منبع اندازه گیریه که برای هر دو مدل وابسته و مستقل نحوه اتصالات تو تصاویر نشون داده شده.
سلام وقت وقتتون بخیر
میخواستم ببینم اطلاعات ولتاژ و جریانی که این ماژول میخونه رو میشه در کامپیوتر ذخیره کرد؟
میخام دیتای ولتاژ و جریان رو نسبت به زمان رسم کنم اگر میشه راهنماییم کنید
برنامه نویسی تا حدودی بلد هستم اما تا به حال این کار رو انجام ندادم اگر ممکنه یه مثالی یا سر نخی به من بدید تا خودم بتونم ادامه کار رو پیش ببرم
متشکرم
سلام
این برد خیلی کاربرد داره تو صنعت برای ارتباط سنسور دما به plcاز طریق مد باس ولی حیف که مستنداش به زبان چینی نوشته شده فقط.
