1. A complex and unusual rule. This was s specialist electronics rule designed by Chan Street for Pickett.
2. The front side of the rule has most of the critical scales from the Log Log Dual Base Speed Rule set however there were some changes to some scale arrangements to suite some typical calculations used by the electronics engineer.
3. The scales on the back of the rule are designed for electronics type calculations with many of the scales referring to four of the central scales which are based on time variable functions. For a detailed explanation of these scales refer to the manuals available on the Documentation Download Page.
4. For a more detailed image of the scales on the back and the accompanying legend refer to the large image to the left.
