Measurement Grid (9×6 = 54 points)

🎯 Grid Methodology (n-1 vs n Principle)

Understanding the Measurement Pattern

Longitudinal (X-axis):

n lines marked on the plate
n-1 measurements between lines
Example: 9 lines = 8 measurement intervals
Formula: Effective length = (n-1) × step

Transversal (Y-axis):

n lines marked on the plate
n measurement points along each line
Example: 6 lines = 6 measurement points each
Total grid points = n × n

Industry Standard: This (n-1 vs n) pattern follows Wyler, ISO 1101, and IS 2285/7327 standards for surface plate calibration.
