You can read it either way and obtain the same results Note: Maximum micrometer setting possible with Small Powder Bar What is in Column M? The chart is plotted using data from calculation fields in column M, which is partially hidden to prevent confusion. The cells in column M contain an equation that returns a value of #N/A if there are no charge weights entered. This is done to make the chart and curve fit equation ignore empty data cells. You may never need to edit the cells in column M and can just leave it hidden. If you add rows to this spread sheet, you should expose Column M and check those cells in case they need editing Note: Although more micrometer settings are shown, you only need to measure data for the settings in bold, plus the maximum setting 6.25 for that powder bar, to obtain a general calibration curve for a new 6.50 powder. If you have the time, or are using a powder that is 6.75 particularly difficult to meter, you can add more settings, or measure 7.00 settings only in a narrow range around your desired powder weight 7.25 as needed to enhance calibration curve accuracy Slope (m) UniqueTek, Inc. y-intercept (b) Rev. 4 4/16/12 R Charge weight values should be considered supspect if R2 is less than
