DescriptionThis inclinometer (angle measuring device) can be used to measure angles within ±180° (0 ~ 360°) range in wide variety of applications. You can simply place the meter on a reference surface zero， then it will give a result of measured angle within 0.3° accuracy.The built-in strong disk magnets on the bottom can firmly attach the meter to the surface you are going to measure， so that you can easily and quickly set the bevel angle. The reading is always displayed as upright. This meter works great for miter and table saws.Feature- Absolute&Relative angle measurement- Magnetic base securely attaches gauge to any metal surface- Large LCD display reads upright at any angle- Degree & slope conversion，- Platform monitoring - Drainage angles and run-off slopes - Grader and tractor work alignment - Setting blade angle of Circular Saws - Setting blade angle of Miter Saws - Tool setting on Lathes - Setting work piece angle for milling - Check drill press table setting， table saw， jointer table， band saw， jointer fence or band saw table - Data hold.- Calibrate button- Runs on by 3 pcs CR2032 3V batteries(battery not including for air shipment)Specification: - Measuring Range: 4 x 90° - Resolution: 0.1°/ 0.01% - Repeat-ability: ±0.1° - Operating Temperature: 0 - 40°C - Operating Humidity: 40 - 80% - Power Supply: 3 x 3V CR2032 Batteries- Size: 65 x 52 x 26 mm (2.6" x 2" x 1" inches) - Weight: 128gFunctions:1. Absolute angle measurementPress ON/OFF button and the unit will directly enter the state of absolute angle measurement. It will display the angle between the measured surface and the level. When the angle between the working surface of the unit and the level changes， the angle value changes accordingly. When the two indicating arrows on both sides of the LCD display appear， they show that the working surface of the unit is not on the level. 2. Relative angle measurementPut the unit’s working surface on one surface， press ”Calibrate” button for 1-2 seconds， “0.00°” is displayed. Then move the unit to other surface to be measured， the displayed value will be included angle of the two surfaces. Press ”Calibrate” button for 3-5 seconds， it will change to the state of absolute measurement.3. Upright displayThe displayed value would be not upside down whatever the unit is upside or not.Package- 1 x Bevel Box with Spirit Level- 3 x 3V CR2032 Batteries (installed)- 1 x English Instruction Manual
