7.3. Levelling: 4-Load-Cell Platform Scales To level the scale use the levelling feet and the level indicator. Each foot can be turned left and right, turning causes tilt. Adjustment span of the scale level is narrow therefore the correct level is obtained using steel washers which are to be put under the feet. -

Page 17: Good Weighing Practice: 1-Load-Cell Platform Scales
10.1. Good Weighing Practice: 1-Load-Cell Platform Scales In order to guarantee a long-term operation, wherein correct measurements are provided, the following principles must be adhered to: Load the weighing pan steadily, avoid applying mechanical shocks. Place the loads centrally on the weighing pan (eccentricity errors are specified by EN 45501 standard, point 3.6.2). -
