On the base of its high altitude and nearly full coverage, the ARGO-YBJ experiment could play an important role in understanding the energy scale. In this work the light component (proton + helium like) of cosmic rays can be selected from the shower lateral information. By combining the westward displacement of moon shadow position due to the effect of the geomagnetic field, we carefully checked the relationship and its systematic error in determining shower primary energy from the shower size. The construction of an energy scale for the measurement of spectrum of the cosmic ray light component below few tens TeV is then discussed.
