How many 3/16 shims are typically used in the calibration process?

In the calibration process for asphalt paving equipment, using four 3/16-inch shims is typical because they provide a precise and stable platform for ensuring the accuracy of the equipment. This quantity strikes a balance between providing enough adjustment capability while maintaining the stability needed during calibration. The use of four shims helps to accommodate variances in the machinery setup and ensures that the calibration accurately reflects the intended specifications for the paving process.

Utilizing fewer than four shims might not offer the necessary adjustment range or stability, and using more might complicate the calibration with unnecessary complexity, thereby making it harder to achieve the desired precision. Thus, four shims are generally accepted as a standard practice in calibration to ensure the equipment operates correctly within industry standards.
