A traffic cop is an officer that works within the traffic bureau of the police department. Traffic cops are responsible for the safety of all motorists, bicyclists, and pedestrians on the roadways.They patrol roads, issue tickets and direct traffic.o be hired as a traffic cop, interested candidates must apply to the police department. 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.
3 Adjusting the calibration interval In response to customers seeking to reduce instrument cost-of-ownership, we have developed a formal âcalibration interval extensionâ process. The process has two major steps: checking for data sufficiency and, if enough data is avail-able, performing detailed statistical analyses. Part 2: Performing the statistical analyses If the model under review passes the data-sufficiency tests, then the statistical analyses can proceed. The specific methodology depends on three things: the type of instrument, the length of the existing calibration interval and the sample size.
