1. Step-on technology: when the scale has weight above 10KG(22LB) on it, the 4 high accuracy sensors will work immediately, you needn't open it manually; auto power-on when sensors sense weight, and auto power-off 8 seconds later after it there's no weight on the scale
2. Two measurement units: LBS and KG. you can switch them freely by pressing the button on the back of the scale
3. Non-calibration before weighing: all our scales was calibrated twice before they're packed, you needn't calibrate weight again. as long as the scale is aclinic and on hard surface, just step on it, and value in the display screen is your real weight

5. Maximum weight is 180KG(397LB), minimum weight is 0.2KG(0.44LB). if weight is between it, we guarantee it's accurate; if beyond it, we suggest you use other scale
