chart2 Wiring diagram
The wiring of this module is divided into two parts: voltage and current test input terminal wiring and serial communication wiring, as shown in the diagram above.2According to customers\` actual needs, they should cooperate with different customers.TTLThe transfer board realizes communication with different terminals.
D.Display interface
The instrument display is displayed on the host computer or other terminals, and the display interface of the host computer is as follows.1The following is a brief description of the display of the parameters:
1.Voltage display
Measure and display the current power frequency grid voltage.
2.Current display
The current load (Electrical) current is measured and displayed.10mABut this module belongs to high-power test equipment, such asmAThe level of current test accuracy is not recommended for care.
3.Electric quantity display
Measure and display current cumulative power consumption.;
It is necessary to add that the smallest unit of electricity metering in this module is0.001kWh,That is,1WhIt starts to accumulate. The resolution is relatively high, for low power.100WThe load test is more intuitive than the load test.
4.Power display
The current load power is measured and displayed.0.001kWThat is,1WThe module is a high-power testing device, for example.1WDo not use the required test within the power test.
E.Serial communication
This module is equipped withTTLSerial data communication interface, through the serial port can read and set the relevant parameters, but if you want to connect withUSBorRS232Communication of devices (such as computers). Then you need different hardware.TTLTransfer board (USBCommunication needs to be equippedTTLturnUSBSwitchboard;RS232Communication needs to be equippedTTLturnRS232Switchboard) ,The detailed connection mode of the transfer board is shown in detail.2.
