Electronic device with graphical user interface for graphical display and functional measurement

Abstract

1. Name of the product in this design: Electronic device with graphical user interface for graphic display and functional measurement. 2. Intended use of this design: for use in an electronic device. 3. The key design features of this product are: the design of the graphical user interface. 4. The image or photograph that best illustrates the design's key features: the front view. 5. For electronic devices, the rear view, top view, bottom view, left view, and right view are omitted due to conventional design. 6. Purpose of the graphical user interface: used for function indication and display of measurement values ​​during measurement. 7. Human-computer interaction method of graphical user interface: The main view is the display interface when the instrument is turned on, which measures DC voltage; when the user rotates the knob to the AC voltage range, the AC voltage measurement function is activated, and the interface changes as shown in Figure 1; when the knob is rotated to the NCV / Live range, the instrument defaults to the NCV function, and the interface changes as shown in Figure 2. When the upper part of the instrument is close to the live AC power line being measured, the instrument will emit a "beep, beep" alarm sound, and the interface changes as shown in Figure 3; pressing the F2 button on the instrument switches to Live mode. The function is as follows: Enter the interface state change diagram 4; Insert the red probe into the fourth jack of the instrument, and when the probe tip touches the measured position or socket, an alarm sounds, indicating that the measured point is a live wire, and enter the interface state change diagram 5; Rotate the knob to the AC current range, at which point the AC current measurement function is activated, and enter the interface state change diagram 6; Rotate the knob to the DC current range, at which point the DC current measurement function is activated, and enter the interface state change diagram 7; Rotate the knob to the capacitance range, at which point the capacitance measurement function is activated, and enter the interface state change diagram 8; Rotate the knob to the diode / continuity range, at which point the instrument defaults to continuity function, and enter the interface state change diagram 9; Press the F2 key to switch to diode function, and enter the interface state change diagram 10; Rotate the knob to the resistance range, at which point the resistance measurement function is activated, and enter the interface state change diagram 11; When the F1 key is pressed, the instrument displays the system setting interface function, and enters the interface state change diagram 12; Press the F3 key again, and the instrument displays the automatic shutdown time setting, and enters the interface state change diagram 13; Continue pressing the F3 key. Press the button to sequentially display brightness adjustment, sound settings, temperature settings, language settings, firmware update, and factory reset functions, respectively entering the interface change states shown in Figures 14 to 19; press the F1 button on the instrument again to exit the system settings interface; when the instrument needs to be charged, connect the USB cable to charge, and the instrument will enter the interface change state shown in Figure 20. At this time, the instrument is prohibited from use. If you need to use it, please unplug the USB charging cable. 8. Other situations requiring explanation: This display panel is used for digital multimeters.
