Feature:1. LCD digital display, it can display the reading more clearly to ensure the accuracy of the reading.2. Accurate range, which can ensure more accurate measurement and minimize measurement errors.3. Using piezoelectric ceramics, its measurement is more accurate and comes with a replacement probe, which can extend the service life.4. Small size, portable and light weight, it can be easily handheld to measure in various situations.5. It is suitable for mechanical fault detection, vibration testing, and can help troubleshoot obstacles.How to Use:Measurement Mode Setting:Use the measurement mode selection switch to select the measurement mode: high‑frequency acceleration (H); acceleration (A); velocity (V); displacement (D).Measuring:1. Place the sensor (with magnetic base) on the object to be measured and press the M key to measure.2. When the vibration value display is stable, release the M key and the vibration display value will be maintained, and the value can be read at this moment, and it will automatically shut down after 15 seconds.3. When measuring, the contact between the probe (built‑in acceleration type) and the surface of the measured object should be at right&nbs
