3. Operating Instructions
3.1 Taking Measurements
Place the base of the DWL280PRO firmly against the surface you wish to measure. The bright LED display will instantly show the angle or slope.
3.2 Changing Measurement Units
The DWL280PRO allows switching between different measurement units. Use the mode button (often indicated by a gear or unit symbol) to cycle through degrees (°), slope (%), mm/M, and inch/FT. The current unit will be displayed on the screen.
3.3 Auto-Invert Display
For convenience when working in awkward positions, the display automatically inverts when the gauge is held upside down, ensuring the reading is always upright and easy to read.
3.4 Buzzer Function
The device features a buzzer that sounds at 0 degrees or any user-set angle, providing an audible indication of level or target angle achievement.
3.5 Magnetic Base and V-Groove
The integrated magnetic base allows the level to securely attach to metallic surfaces, freeing your hands for other tasks. The V-groove design on the base ensures stable placement and accurate measurements on cylindrical objects like pipes.
