What can happen when we use an accuracy specification and assume all the measurements are centered to the specification limits? Not correcting for Measurement Bias is a typical problem in the metrology community, where many papers assume a centered process or Measurement and that any known Measurement Bias has been corrected.
The Morehouse technical paper on Measurement Bias examines what happens if we fail to correct for Measurement Bias.
Not correcting for Measurement Bias matters because when a known bias is ignored, meaning not corrected or not included in the Statement of Measurement Uncertainty on the Calibration Certificate, measurement traceability may not be fully achieved, and all subsequent measurements are suspect.

Several organizations and publications reference or insist on maintaining a 4 to 1 TUR (Test Uncertainty Ratio) without understanding the level of risk that they may be subjecting themselves to. The general thought is if the lab performing the calibrations has standards at least four times better than what they are calibrating that everything is good. This paper discusses TUR, PFA Risk, and why the location of the measurement matters. We will discuss two managed risk guard banding methods (5 & 6) found in the ANSI/NCSL Z540.3 Handbook. We will show that a 4 to 1 TUR is not enough and can result in a 50 % risk.
The differences Between ASTM E74 and ISO 376 can be confusing. Morehouse has been performing both ASTM E74 and ISO 376 calibrations for more than fifteen years. We have been calibrating in accordance with the ASTM E74 standard since its introduction in 1974, and performing ISO 376 calibrations since sometime in early 2000. Until recently, we assumed that the rest of the world and force community knew that the standards were completely different and that either standard could not be substituted for another. This paper explains those differences in more detail.

This is a one-sheet Verification For Morehouse Calibration Software verifies the software converts the mV/V values properly. The end-user must verify they have entered the coefficients correctly
Morehouse software for 4215 V1.0.6: (click to download)
2022 version Morehouse software for 4215, uses the coefficients from the calibration report, typically ASTM E74 or ISO 376 report to ensure the mV/V values can be converted to engineering units. Keeping the calibration in mV/V is important as any adjustments are made by issuing new coefficients at the time of calibration. This keeps the cost down and allows the end-user the ability to easily compare the stability from one calibration to another.
Morehouse software for 4215 also allows adjustments to other engineering units such as N, kN, kgf, & lbf. In addition, the software allows for multiple load cells to be summed together for weighing or other applications where each load cell can be monitored as a percentage of the overall applied load. This feature may be useful for calibrating pipe testers, large force machines requiring several load cells, or checking the center of gravity.
In addition, Morehouse software for 4215 can convert force to mass values such as lb, kg, grams, and ounces which is helpful for the calibration of scales.
