zmart Digital Inclinometer, Digital Angle Sensor, Angle/Gradient Level Meter with Beveled Magnetic Base

This digital angle meter uses a 9V battery. Features include: Two built-in magnets on the measuring surface, which allow it to be attached to the workpiece for convenient measurement. Lightweight and durable. Three function keys, data hold function, zero setting at any position, quick display of measurement values, optional auto power-off, 1-year battery life, readable display with right-to-top orientation, portable size, convenient for use with other measuring tools to expand the measurement range, relative/absolute measurement at any position, suitable for angle measurements in automotive, woodworking, construction, drilling, and other applications. Technical Parameters: Measuring Range: 360°, Resolution: 0.05°, Accuracy: 0.2°, Repeatability: 0.1°, Battery: AAA batteries (not included), Operating Temperature: 0 to 45°, Dimensions: 57x57x30.5mm Instruction Manual: Press the "On/Off" button to illuminate the LCD screen and display the absolute horizontal angle. Press the "On/Off" button again to turn it off. When starting measurement, the LCD monitor will initially display 0.0. If " appears on the left side of the LCD, it means that the left side is higher and lower than the right side. Place the measuring device on a level stand and press the "ZERO" button. The value will return to zero, and the readout will be the angle value measured relative to the level stand. Press the "HOLD" button to lock the value on the screen. Use the magnet on the bottom to attach the measuring device to an iron object and press the "ZERO" button. Reset the value to continue relative measurement.
