Other Topics Related to Measurement Uncertainty
This section discusses other important topics related to measurement uncertainty.
The first involves estimating the uncertainty of a field calibration, where a reference
standard stopwatch is brought into the field and used to calibrate another device. Next,
the stability and aging of 32 768 Hz quartz crystal oscillators used in stopwatches and
timers is discussed, followed by discussions of how the performance of a stopwatch
can change when a new battery is installed, and how extreme temperature conditions
can affect stopwatch performance.
