The scales should be consistent with the intended functional use of the data.
Additional Information:
Scales should be selected to (1) span the expected range of operational parameters, (2) employ appropriate scale ranging techniques, or (3) be supported by auxiliary wide-range instruments. For example, the monitoring of neutron flux at reactor trip must have a variable scale of 0 to 100 percent of the design value and a time scale resolution of seconds. However, post-trip monitoring may have a variable scale of 0 to 10 percent with a time scale resolution of minutes. Finally, operational log data of neutron flux may have a time scale resolution of hours.
