USER WARNINGS RECOMMENDATIONS FOR THE PROPER USE OF WEIGHING INSTRUMENT Keep away from heat sources and direct sunlight Repair the instrument from rain (except special IP versions) Do not wash with water jets (except special IP versions) Do not dip in water Do not spill liquid on the instrument Do not use solvents to clean the instrument Do not install in areas subject to explosion hazard (except special Atex versions) -
Page 6: Recommendations For Correct Installation Of The Load Cells
RECOMMENDATIONS FOR CORRECT INSTALLATION OF THE LOAD CELLS SIZING OF LOAD CELLS CAPACITY For safety reasons, in case of static weighing, it is advisable to use the load cells at a maximum of 70-80% of its nominal capacity (assuming that the load is uniformly distributed over the entire weighed structure);... - Page 7 EARTHING THE WEIGHED STRUCTURE By means of a copper wire with suitable cross-section, connect the cell upper support plate with the lower support plate, then connect all the lower plates to a single earthing system. Electrostatic charges accumulated because of the product rubbing against the pipes and the weighed container walls are discharged to the ground without going through or damaging the load cells.

Page 19: Real Calibration (With Sample Weights)
REAL CALIBRATION (WITH SAMPLE WEIGHTS) After having performed the THEORETICAL CALIBRATION, EQUALIZATION and TARE WEIGHT ZERO SETTING, this function allows correct calibration to be done using sample weights of known value and, if necessary, any deviations of the indicated value from the correct value to be corrected. -
Page 20: Confirmation And Change Of Active Channels

Page 21: Equalization
EQUALIZATION At the end of the equalization you must perform the TARE WEIGHT ZERO SETTING and, if necessary, the REAL CALIBRATION. REAL EQUALIZATION Use a sample weight equal to at least 50% of the single load cell capacity. : unload the scale, wait for stability and confirm by pressing ENTER. -
Page 22: Filter On The Weight
FILTER ON THE WEIGHT Setting this parameter allows a stable weight display to be obtained. Two filter types are available: - : Laumas standard filter (default); - : moving average filter with fixed refresh frequency. To increase the effect (weight more stable) increase the filter level (from 0 to 9, default 4). -
Page 23: Anti Peak
ANTI PEAK When the weight is stable, the anti peak filter removes any sudden disturbances with a maximum duration of 1 second. Confirm the filter on the weight with ENTER and select one of the following options: - : anti peak filter enabled (default); - : anti peak filter disabled. -
