Measuring Range: 4× 90o? Working Temperature:0 o C-40 oC ? Resolution: 0. 05o? Relative Humidity: 40%-80% ? Accuracy: ± 0. 05o? Dimension: 54× 54× 20mm ? Battery Type: 3V CR2032 ×3 3. Functions (1) Absolute angle measurement Press ON/OFF and the unit will directly enter the state of absolute angle measurement (No matter change the batteries). 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. For example, when the ar row “↓” on one side appears, it shows that this side is under the level. It needs to move up this side of the unit to reach the level. The arrow “↑” shows that it above the level. when the
