Features EASY TO USE: The digital angle gauge support any angle measurement at 4×90°, and the reading is automatically flipped to facilitate data viewing FLEXIBLE SWITCHING: The digital angle finder support free switching of angle or slope by pressing MM/M, %, ° keys MULTI ANGLE MEASUREMENT: The digital angle finder can also measure relative angles easily by pressing ABS/REF key to convert BIAXIAL MEASUREMENT: The bevel gauge inclinometer support simultaneous measurement of two axes for a wide range of applications. The X axes angle α is ‑17.5°. The Y axes angle β is 23.3° WITH MAGNET: Magnetic digital angle gauge built in magnet, adsorb to measured workpiece, not easy to slide or drop Specification: Item Type: Digital Angle Gauge Measuring Range: Single Axes: 4x90°, Double Axes: ±60° Resolution: 0.1° Accuracy: Single Axes: ±0.2°, Double Axes: ±0.3° Repeatability: 0.1° Power Supply: 3.7V lithium battery 300mah Charger Interface: DC5V 400mA (Type C) Use Environment: 0-40℃(humidity not more than 80%) Magnet: Magnetic adsorption measuring surface, which can be adsorbed on the workpiece to be measured Datum: Absolute zero point measurement with the horizontal plane as the datum How to Use: Power ON: In the shutdown state, press the ON/OFF/REF key to power on. Power OFF: Hold down the ON/OFF/REF key to power off. (the product will automatically shut down after being stationary for 180 seconds) Relative Angle Measurement: The absolute angle measurement mode is entered by default after starting up. (relative measurement mode means that the current angle is used as absolute 0 to measure the angle change caused by horizontal body displacement.)
