READ A RULER HOW TO

I will explain how to check for accuracy in a later step.)īefore using a slide rule new to you there is a preliminary check for accuracy that should be made. If a reading is not quite accurate, try a different browser and see if that solves the problem. (Note: In my experience, some browsers may introduce some inaccuracies when using this virtual slide rule. Sweep your computer's cursor over key areas of the graphics to find any text boxes if you do not see them. They are not always easy to see because the N600-ES slide rule used an eye saver (ES) yellow and black color scheme.

Some, but not all graphics in this Instructable do utilize text boxes.

Because of all of its scales and features, a slide rule really is a full scientific calculator for all types of multiplication and division problems. Just be aware that this rule has two sides with additional scales on the backside. If you go to this virtual slide rule on the Internet, you will see a radio button on which you can click to display the scales on the back side of this virtual slide rule. Different makers of slide rules arranged the scales slightly differently according to what each maker thought would make its rules more user friendly. From the top down you can see the LL1 or log-log 1 + and - scales the A and B scales the ST, T, and S scales the C and D scales the DI (D inverted) scale, and the K scale. The graphic shows the left end of the virtual slide rule with the various scales. It is highly recommended that you open a second browser window and bring up the virtual slide rule so you can practice each new thing you learn in this Instructable. Clicking and dragging will not work on the graphics in this Instructable. You can also drag the entire slide rule across your screen for a better view. Just click and drag the moving parts at the link above. With the mouse cursor on your computer and your left mouse button, you can work the moving parts on this virtual slide rule just as if you were holding an actual slide rule in your hands. It is the slide rule shown in the graphics. You do not need your own slide rule because this Instructable will make use of a virtual Pickett N600-ES slide rule available for anyone to use at this link.

You may want to download a PDF copy of this Instructable to your computer so you can learn the material in small bits. It takes time and practice over days, perhaps even weeks, for the principles to become part of the learner. Still, learning to use a slide rule is not a simple afternoon project.

It will cover all of the basic calculations, not just multiplication. I aim to make this one more complete and easier to follow. There are already a couple of tutorials posted at Instructables on using a slide rule. A member at Instructables asked me to explain how to use a slide rule for the sake of those who came along about the time electronic calculators replaced slide rules.
