Routines and Procedures to Test the Accuracy and Precision of Digital Dietary Scales Used in Quantitative 24-Hour Dietary Recall Surveys

This Intake survey guidance describes recommended routines and procedures to test the accuracy and precision of digital dietary scales during all phases of survey work - before first use, during standard recipe data collection, during survey training and piloting, and during data collection (both weekly, and after set-up but before collecting any data during the 24-hour dietary recall interview). Recommended specifications for digital dietary scales for use in quantitative 24-hour dietary recall surveys are provided in a separate Intake survey guidance document, available here.
