A display with more digits can look reassuring without resolving the measurement problem. The complete method and its influencing conditions still matter.
NIST's uncertainty terminology distinguishes measurement concepts that should not be used interchangeably. NIST — Measurement uncertainty terminology.
Examine the whole method
For a flexible product dimension, positioning and reference-point interpretation may influence the result alongside the instrument. Extra display digits do not remove those contributions.
Report a meaningful result
Ask the responsible measurement specialist to define an appropriate uncertainty and reporting basis. Avoid presenting every displayed digit as justified information. The useful result supports the intended comparison with a known method and limitation, rather than merely appearing more precise than another instrument's display.
