Single pan mechanical substitution balance maintains  consistent response throughout the useful capacity is achieved by  maintaining a constant load on the balance beam</ins>, <ins style="font-weight: bold; text-decoration: none;">thus the fulcrum, by  subtracting mass on the same side of the beam to which the sample is  added.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">Electronic analytical scales measure the force needed to counter the  mass being measured rather than using actual masses.
