Candidates need to have high school diplomas or the equivalent; they also need to be at least 21 years old and be U.S. citizens.
Step 3. Use the equation of the calibration curve to adjust measurements taken on samples with unknown values. Substitute the measured value as x into the equation and solve for y (the true value). In the example from step 2, y = 1.05x + 0.2. Thus, a measured value of 75.0, for example, would adjust to y = 1.05(75) + 0.2 = 78.9.
An Improved High-Precision Calibration Procedure. For Reference Standard Hydrometers. Horace A. Bowman and William H. Gallagher. Institute for Basic Standards, National Bureau of Standards, Washington, D.C. 20234. (June 24, 1969) This paper describes a method of calibrating hydrometers which. although no more accurate. that the technique used heretofore at the National Bureau of Sta ndards, reduces calibration time.
