At the time of purchase in the description text was both a 500g / 0.01g mode and a 2000g / 0.05g mode the speech, the latter can not but the scale. Calibrated the scale is so far not discernible when one weighs paperclips, minimal distortion of the measured values can be determined, the PCS function should therefore be very accurate. (0.01--0.02g inaccuracy between measurements with ~ 325g difference in weight)
