The PRO-360 and PRO-3600 are certified for light industrial environments and conform to the requirements of the EN50082-1:1992 standard. The protractors have passed tests for EMI and RFI compliance as part of our testing for the CE Mark Declaration of Conformity. The unit operates for up to 500 hours on a single 9V battery, incorporates an automatic power down feature, and ships standard with a rigid plastic case.
Unit can be recalibrated to factory accuracy in the field without special tools or fixtures. Maximum accuracy of +/- 0.1° and maximum resolution of 0. Easy to read LCD display which intelligently flips over when the unit is upside down. The unit can also be easily recalibrated in the field to factory accuracy using any available flat surface. The front panel buttons can be used to capture desired readings or to designate an alternate reference surface from which subsequent angles are then measured. The frame is grooved along the bottomsurface to facilitate use with round objects such as pipes or shafts and incorporates threaded holes on the bottom for rigid attachment if desired. The unit utilizes a patented, liquid-filled sensor combined with precision measurement circuitry to provide unparalleled accuracy and stability.Ī precision machined aluminum frame provides a rigid, lightweight, ultra-precise platform for extremely accurate measurements. The PRO 360 Digital Protractor from SmartTool Technologies is a revolutionary measuring tool that provides an immediate, digital reading of all angles in a 360° range. Both protractors can be easily fitted with an available, magnetic base or an array of custom attachments. The PRO 3600, in addition to higher resolution (0.01°), has an RS-232 port so you can output the angle measurement data to a computer. They also have "Alternate Reference" (Alt Zero) which allows you to electronically zero the reading anywhere within the digital protractor's 360° range. * These state-of-the-art, angle measurement tools have features such as "Hold" which lets you to store the last reading taken with a touch of a button. This video will show you all the best practices. You can set the protractor accurately using several methods. This unit has a One Year Limited Warranty, CE Certification and National Stock Numbers. SketchUp Training Series: Protractor tool The protractor in SketchUp creates construction lines to help you while drawing and inferencing.

Use your own image with the interactive protractorĬlick the “Custom Image” and enter a link to a publicly accessible image URL as the background, then use the overlay interactive protractor to measure various angles on your own worksheet. Print out the 6 questions as a PDF (the protractor image will not be included) and practice using your own “real” protractor to measure the angles. Download the questions as a PDF worksheet Share the link with all your remote students during zoom class and practice measuring the same set of angles, or assign the same set of questions as homework to the whole class. Use the URL displayed at the top to load the same set of angles. Keep practicing with new questionsĬlick the “New Questions” button to generate a new set of questions. Make sure you are reading off the correct set of markings. Note: there are two scale markings corresponding to left-to-right ( black) and right-to-left ( blue) angle measurement. Angles within 2 degrees will be marked as correct. Check your answersĮnter your answers in the respective boxes, then click “Check Answers” button to check your answers. Protractor is highlighted in red when rotating. Rotate the on-screen protractor using (desktop) shift-key + left mouse drag or (tablet) two-finger touch and rotate. Protractor is highlighted in green when moving. 
Move the on-screen protractor using (desktop) left mouse drag or (tablet) single finger touch and drag. Using the interactive protractor app on screen To use it, align the horizontal line on the protractor to one of the two lines that make up the angle you want to measure, then read off the angle on the appropriate scale on the curve edge of the protractor.
