- Calibration Function: Ensure precise measurements with our advanced calibration feature. It eliminates errors from internal components, resulting in more accurate test results. Choose between quick calibration for efficiency or full function calibration via the function menu, which requires an additional 220nF capacitor. - Frequency Measurement: Accurately measure frequencies ranging from 1Hz to over 1MHz. For frequencies below 25KHz, the device displays the corresponding period, making it easy to analyze low-frequency signals. - F-Generator: Experience versatility with the square wave generator. Select from multiple square frequencies by turning the test button left or right. To exit the square generator, simply long-press the test button. - 10-bit PWM: Utilize the pulse generator to adjust the duty cycle of pulses from 1% to 99%. This feature allows you to customize signal output according to your specific needs. Press and hold the test button to exit the pulse generator. Applications: 1. Electronics Testing: Ideal for technicians and engineers testing circuits, allowing for precise frequency and pulse measurements. 2. Signal Generation: Perfect for generating square and pulse signals in educational settings or for DIY projects, providing hands-on experience with waveform manipulation. 3. Calibration Tasks: Essential for calibration of measuring instruments in laboratories, ensuring high accuracy in experimental setups. With its compact size and robust functionality, this tester is a reliable tool for professionals and hobbyists alike, ensuring accuracy and flexibility in various applications.
