Technical Parameters: ① Measuring range: 0-90°x 4 ② Resolution: 0.05° ③ Accuracy: ±0.2° ④ Repeatability: 0.1° ⑤ Battery: 9V battery ⑥ Working temperature: 0°C-40°C ⑦ Dimension: 57*57*30.5mm ⑧ With 3 diameter 10mm built-in magnets in measuring surface, which if convenient to be attached to the object measuring workpiece. ⑨ Absolute zero measurement based on the horizontal surface. ⑩ Net weight: 0.21kg Operating Instructions: ① Press the "ON/OFF" button, it turns on, and the LCD displays absolute horizontal angle. Press "ON/OFF" button again, it turn off. ② Measurement initially displays 0.0°on the LCD at the beginning, when it displays""on the left side ""on the right side, it means the left side is higher and right side lower; when it displays"" on the left side ""on the right side, it means the left side is lower and right side higher. ③ Put the instrument on the horizontal stand, and press the "ZERO" button, the value returns to zero, and the read-out is the angle value measured angle value relatively to the horizontal stand. ④ Press the "HOLD" button, the value on the screen will be locked. ⑤ The magnets at the bottom allow the instrument to be attached onto iron material measurement object. Press the "ZERO" button; reset the value to proceed relative measurement. Application: More widely application is in wood processing industry (especially in furniture manufacturing industry) for wood angle accurate cutting; auto repair industry for tiring assembling angle accurate controlling; in machining industry for machine tool working angle accurate positioning, and large vehicle arm rotation angle etc.
