FA-102 CT Volt-Ampere Characteristic Tester Function Description and Main Menu
Edit
FA-102 LCD Display Description
This instrument uses a 320×240 high-resolution gray backlit LCD display, which can be clearly seen even in strong sunlight. The test process, test environment settings, and test results are all displayed on the LCD screen, with a full Chinese operating interface, clear graphics, beautiful appearance, and easy operation.
FA-102 Rotary Mouse Usage Instructions
The rotary mouse functions similarly to a computer mouse, with three operations: "rotate left", "rotate right", and "press to select". Through these three operations, you can move the cursor, input data, and select operations.
Move cursor: You can move the cursor by rotating the mouse left or right. Move the cursor to the desired option and "press" the knob to select it.
Data input: When you need to modify or input data, move the cursor to the option you want to modify, press the mouse, and enter the hundreds or tens digit modification operation (the cursor shrinks to the digit being modified). Rotate the mouse left or right to increase or decrease that digit.
Press the mouse to confirm the modification of that digit and move to the next digit, similarly rotating left or right to adjust. After modifying all digits one by one, the cursor enlarges to full size, exiting the data modification mode. You can then rotate the mouse to move the cursor away.
FA-102 Power-On Interface and Main Menu Introduction
First, connect the AC220V or AC380V power supply to the instrument panel, turn on the power switch on the panel, the LCD white backlight will light up, and the device will perform self-check. After self-check, it enters the Chinese main menu of the Volt-Ampere Characteristic Tester (as shown in Figure 2.1).
After entering the Chinese main menu, the cursor indicates the current test item as "Volt-Ampere Characteristic" measurement, and the background of the currently selected item will be inverted. Press the rotary mouse to enter the Volt-Ampere characteristic test interface. Rotate the mouse to select "Ratio Polarity", "Polarity Measurement", "Set Time", or "PC Communication".
FA-102 PC Communication
This instrument uses an RS232 communication port to connect with a PC. Use an RS232 cable or a USB-to-RS232 converter to connect the instrument to the PC, and select the PC Communication option. The instrument then enters the PC communication state (as shown in Figure 2.2). For specific operations, refer to Chapter 5 for application software installation and usage instructions.
After the instrument is successfully connected to the computer, the test personnel can view historical data stored in the instrument's Flash on the computer, or use the computer to control the device for CT polarity test, CT ratio polarity test, CT volt-ampere characteristic test,
and save the test results, print them as A4 documents, and export the data to Excel format. All real-time data collected during the test will be displayed in the software oscilloscope of the application software. The application software can also calculate the CT error curve corresponding to the CT volt-ampere characteristic test based on the test results. After the connection is finished, you can press and hold the reset button to restart the device and exit the connection interface.
FA-102 Modify Time and Date
In the instrument standby screen, select the "Set Time" option, and after confirmation, enter the time setting interface (as shown in Figure 2.3). You can set the year, month, day, hour, and minute parameters of the instrument by rotating the mouse.[1]
