Page 5: User Warnings
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 WELDING: Avoid welding with the load cells already installed. If this cannot be avoided, place the welder ground clamp close to the required welding point to prevent sending current through the load cell body. WINDY CONDITIONS - KNOCKS - VIBRATIONS: The use of weigh modules is strongly recommended for all load cells to compensate for misalignment of the support surfaces.

Page 7: Load Cell Input Test (Quick Access)
LOAD CELL INPUT TEST (QUICK ACCESS) From the weight display, press for 3 seconds: the display shows the response signal of each load cell ( ÷ ) expressed in mV with three decimals. Example: a load cell with 2.000 mV/V sensitivity provides a response signal between 0 and 10 mV. LOAD CELL TESTING Load cell resistance measurement (use a digital multimeter): - Turn off the instrument. -

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
CONFIRMATION AND CHANGE OF ACTIVE CHANNELS After performing the calibration and verifying that the system works properly, you can confirm the channels automatically detected by the instrument; in this way, in case of accidental interruption of the cable of one or more load cells, the instrument displays the alarm. Automatic load cells detection is enabled by default on all 4 channels of the instrument. -
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 : place the sample weight on load cell 1, wait for stability and confirm by pressing : place the sample weight on load cell 2, wait for stability and confirm by pressing... -
Page 22: 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. -
Page 23: Zero Parameters
ZERO PARAMETERS RESETTABLE WEIGHT SETTING FOR SMALL WEIGHT CHANGES (from 0 to max full scale; default: 300; considered decimals: 300 – 30.0 – 3.00 – 0.300): this parameter indicates the maximum weight value resettable by external contact, keypad or serial protocol. -

Page 28: Preset Tare (Subtractive Tare Device)
PRESET TARE (SUBTRACTIVE TARE DEVICE) It is possible to manually set a preset tare value to be subtracted from the display value provided that the ≤ max capacity condition is verified. By default the instrument shows the last programmed preset tare value: to apply it press then After setting the tare value, going back to the weight display, the display shows the net weight (subtracting the preset tare value) and the NET LED lights up to show that a tare has been entered. -
Page 29: Peak
PEAK By keeping the PEAK input closed the maximum weight value reached remains displayed. By opening the input the current weight is displayed. If you wish to use this input to view a sudden variation peak, set the FILTER ON THE WEIGHT to 0. - Page 30 - : 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.
