Scales |
|
| L |
The L scale is a linear log scale used to
obtain the common (log to base 10) of a number on the
fundamental D scale. This scale is normally on the top
or bottom rule, but may be on the slide where it would be
used with the C scale instead. Formula: L = log10 X |
| LC |
The LC scale is used in electronics
calculations to compute the resonant frequency of an
electrical circuit. It is similar to the H scale, but
using different units. Formula: LC = 1 / ( 2π² × X² ) |
| LL |
The LL scale is a log-log scale used to calculate powers. This scale is similar to the LL0 - LL3 scale set below, covering the majority of the range of those scales in one scale, so results are less precise. This scale ranges from 1.01 to 10,000. |
| LL0 |
The LL0 scale is used to raise numbers to
powers greater than one. This is used when the normal
power scales such as A/B, J/K, and F are unsuitable.
These scales allow raising values to non-integer powers. Formula: LL0 = e0.001x |
| LL1 |
The LL1 scale is used to raise numbers to
powers greater than one. This is used when the normal
power scales such as A/B, J/K, and F are unsuitable.
These scales allow raising values to non-integer powers. Formula: LL1 = e0.01x |
| LL2 |
The LL2 scale is used to raise numbers to
powers greater than one. This is used when the normal
power scales such as A/B, J/K, and F are unsuitable.
These scales allow raising values to non-integer powers. Formula: LL2 = e0.1x |
| LL3 |
The LL3 scale is used to raise numbers to
powers greater than one. This is used when the normal
power scales such as A/B, J/K, and F are unsuitable.
These scales allow raising values to non-integer powers. Gauge marks are located at π and τ. Formula: LL3 = ex |
| LL/0 |
The LL/0 scale (or log-log scales) is an
exponential power scales used to raise values to powers less
than one. Formula: LL/0 = e-x |
| LL/1 |
The LL/1 scale (or log-log scales) is an
exponential power scales used to raise values to powers less
than one. Formula: LL/1 = e-0.1x |
| LL/2 |
The LL/2 scale (or log-log scales) is an
exponential power scales used to raise values to powers less
than one. Formula: LL/2 = e-0.01x |
| LL/3 |
The LL/3 scale (or log-log scales) is an
exponential power scales used to raise values to powers less
than one. Formula: LL/3 = e-0.001x |
| Ln |
The Ln scale, or natural log scale is used to
determine the nature log of numbers from the fundamental
scales. Formula: Ln = loge X |
