Abstract

This electronic device is suitable for measuring a quantity.

This measurement device comprises:

• • a unit for measuring the quantity, able to deliver measurement data,
  • an encoding unit, able to convert measurement data into structured data according to a structuration format, the data structured according to the structuration format including at least one portion of the measurement data,
  • a unit for generating at least one two-dimensional matrix code are from the structured data, and
  • a display unit, able to display each generated matrix code.

The structured data further comprise a first identifier of the structuration format, said first identifier being able to identify in a unique way the structuration format.

Claims
