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 18: Maximum Capacity
MAXIMUM CAPACITY : maximum displayable weight (from 0 to full scale; default: 0). When the weight exceeds this value by 9 divisions, the display shows . To disable this function, set 0. TARE WEIGHT ZERO SETTING ... -
Page 19: Real Calibration (With Sample Weights)
REAL CALIBRATION (WITH SAMPLE WEIGHTS) After having performed the THEORETICAL CALIBRATION 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. Load onto the weighing system a sample weight, which must be at least 50% of the maximum quantity to be weighed. -
Page 20: Filter On The Weight
FILTER ON THE WEIGHT Setting this parameter allows a stable weight display to be obtained. To increase the effect (weight more stable) increase the value (from 0 to 9, default 4). As seen in the diagram: - By confirming the message, the currently programmed filter value is displayed. - By changing and confirming the value, the weight is displayed and it will be possible to experimentally verify its stability. -

For the output ±10 V and ±5 V a soldered jumper must be closed (the operation makes the other analog outputs unusable): ▫... - Page 29 - : analog output correction to zero: if necessary adjust the analog output, allowing the PLC to indicate 0. The sign “-“ can be set for the last digit on the left. E.g.: if I use a 4÷20 mA output and, with the minimum analog setting, the PLC or tester read 4.1 mA, I must set the parameter to 3.9 to obtain 4.0 on the PLC or tester.
