These are the sclerometer method introduced by Turner in 1896; the scleroscope method recently invented by Shore; the indentation test adopted by Brinell about 1900; and the drill test introduced by Keep a few years earlier.
Turner's Sclerometer is the method used to test the hardness of minerals.
Turner's Sclerometer - In this form of test a weighted diamond point is drawn, once forward and once backward, over the smooth surface of the material to be tested.

 Testing the Hardness of Metals
The sclerometer is cheap, portable, and easily applied, but it is not applicable to materials which do not possess a fairly smooth reflecting surface and the standard scratch is only definitely recognized after some experience.
The Short test is simple, rapid and definite for materials for which it is suited, but results obtained vary somewhat with the size and thickness of the sample.
The accompanying table gives values obtained on the same materials by the scleroscope, sclerometer, and the Brinell test, the figures being reduced to a common unit, assumed as 1 as a starting point; thus the actual Brinell numerals have been divided by 6, thereby reducing the hardness values for purposes of comparison.

Mineralogical Record: SCLEROMETER and the DETERMINATION OF THE HARDNESS OF MINERALS, THE
After nearly 200 years, Mohs' ten-step hardness scale is still valid as a quick and approximate analytical method for mineral identification.
The sclerometer was invented in the nineteenth century to give a more accurate measurement of mineral hardness, and was used until the beginning of the twentieth century.

 [Jewelry making - Article 00656] - Re: [Orchid] Faceting rough - drilling
With the Mohs' Scale of Minerals being the accepted standard among mineralogists and gemologists, there isn't much published on Sclerometer values for gem materials other than those listed on the Mohs scale.
I do not have access to a Sclerometer myself and have only read about it.
The relative hardness of minerals found on the Mohs' scale appears sufficient for material identification without a need for scientifically exact values.

 [Jewelry making - Article 00718] - Re: [Orchid] Faceting rough - drilling
I see no reason why those Sclerometer readings need to be converted to a logrithmic scale.
Why not just keep the raw measurement data as is? I see no problem in listing the hardness of diamond as Scl (Sclerometer, or whatever shorthand notation for that instrument is appropriate) 140,000.
The more pressing question, I should think, is to determine the best type of instrument to use to make the measurements.
