- Page 2 Protractor's 360° range. The Pro 360 uses an innovative liquid filled angle sensor. As the protractor is moved, the liquid seeks a new position, resulting in changes in the electrical properties of the sensor. A microprocessor analyzes the changes and calculates the numbers seen on the display.
- Page 3 You can also "freeze" any displayed angle on the LCD by pushing the HOLD button. The 360° range of the unit is organized into four 90° quadrants for display purposes. In each, the Pro 360 achieves an accuracy of + 0.1° at level and plumb with a maximum error of + 0.2° in between.
- Page 4 Operating Instructions - Battery The Pro 360 is powered by a 9-volt battery. A new alkaline battery will provide 500 hours of use. A 9-volt lithium battery can be used for even longer life. To extend battery life, the Pro 360 shuts off automatically when left undisturbed for five minutes (to reactivate, push the ON/OFF button).
