The AF-3500 is an all-in-one EMF meter designed for quick and comprehensive measurement of electromagnetic fields. This versatile device offers a user-friendly interface with clear visual feedback and intuitive controls, making it suitable for both casual users and those requiring more detailed environmental assessments. Its primary function is to detect and quantify various types of electromagnetic radiation, including magnetic fields, electric fields, and radio frequency (RF) electric fields.
The core function of the AF-3500 is to provide real-time measurements of electromagnetic fields. Upon activation, the device enters a quick measurement mode, displaying the detected magnetic field strength in milligauss (mG). This mode is designed for immediate environmental scanning, allowing users to quickly identify areas with elevated EMF levels. The device is capable of measuring multiple field types, indicated by its "Multi-Field EMF Meter" designation.
The AF-3500 incorporates a "Data Hold" feature, which allows users to freeze the current measurement on the screen. This is particularly useful when taking readings in hard-to-reach areas or when needing to record a specific value for later analysis. When in Data Hold mode, all measurement readings and functions are locked, ensuring that the displayed value remains constant until the user exits this mode.
The device also includes adjustable brightness settings for its display, offering "Low," "Middle," and "High" options. This ensures optimal visibility in various lighting conditions, enhancing the user experience. Furthermore, the AF-3500 provides independent key selection for different field types (EF, MF, RF), allowing users to focus on specific types of electromagnetic radiation as needed.
A comprehensive "Menu Settings" feature provides access to various customizable options. Within the menu, users can adjust the "Magnetic Unit" (e.g., Gauss/mG, Tesla/µT) and "RF Strength Unit" (e.g., uW/m², mW/m², uW/cm², mV/m~V/m, mA/m, dBm) to suit their specific measurement requirements or regional standards. The device supports multiple languages, including English, Traditional Chinese, Simplified Chinese, Japanese, and Spanish, making it accessible to a broad international user base. Other menu options include "Power off" settings, "Sound" control (enable/disable), and "Information" which typically displays software version details.
Operating the AF-3500 is straightforward, designed for ease of use. To power on the meter, the user simply presses the middle button. The device then displays a startup screen before transitioning into the quick measurement mode, where it immediately begins detecting electric fields. To power off the meter, the user presses and holds the middle button for three seconds.
The device's interface includes dedicated buttons for "HOLD" (left button) and "MENU" (middle button), along with specific buttons for "EF" (Electric Field), "MF" (Magnetic Field), and "RF" (Radio Frequency). These buttons facilitate quick access to key functions and field type selections.
In the measurement mode, pressing the left "HOLD" button activates the Data Hold function, locking the current readings on the display. To return to the measurement mode from Data Hold, the left button is pressed again.
Accessing the main menu is achieved by pressing the middle "MENU" button while in measurement mode. Once in the menu, users can navigate through the options using the right button ("Select"), which moves a blue cursor downwards. To confirm a desired option, the left button ("Enter") is pressed. If the user wishes to exit the menu without making changes, pressing the "MENU" button will return them to the measurement mode.
The brightness settings are adjusted by cycling through the "Low," "Middle," and "High" options, which circulate in a continuous loop. This allows for quick adaptation to changing ambient light. The independent key selection for EF, MF, and RF enables users to toggle between displaying measurements for these specific field types, providing focused readings.
When configuring settings within the menu, such as magnetic units or RF strength units, the right "Select" button is used to move a yellow check mark downwards to the desired option. The left "Enter" button is then pressed to confirm the selection, and the device automatically returns to the measurement mode, applying the new setting. This streamlined process ensures that settings can be changed efficiently.
While the manual does not explicitly detail maintenance procedures such as calibration or cleaning, the design of the AF-3500 suggests a focus on user convenience and durability. The ability to update software versions, indicated by the "Information" menu option, implies that the device may receive firmware updates to improve performance or add new features over its lifespan. The clear and intuitive menu system, with options for language selection and sound control, contributes to the overall user experience and ease of managing the device's operational parameters. The "Power off" settings within the menu might include options for automatic shutdown, which could help conserve battery life and reduce wear on the device. The robust button layout and clear display are designed for regular use, suggesting a durable construction for sustained operation.
