Product Features:
screen display voltage and current, with a MODBUS protocol functions can be used with PC, PLC communication equipment for data collection.
voltage: independent power supply can be measured 0-30V 
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, communication RS485
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 side pin A, B-side for the RS485 interface for Modbus communication
lower side  GND voltage is negative, IIN measurable current use, the VCC when independent power supply module for the power supply positive, non-independent power supply voltage for the positive test, the VIN independent power supply voltage is positive.


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.

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.
