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 CONNECTING SEVERAL CELLS IN PARALLEL: Connect several cells in parallel by using - if necessary - a watertight junction box with terminal box. The cell connection extension cables must be shielded, led individually into their piping or conduit and laid as far as possible from the power cables (in case of 4-wire connections, use cables with 4x1 mm minimum cross-section).

Page 18: 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. -
Page 19: 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 20: 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 24: Limit Mode
INPUTS Default: input 1 = input 2 = input 3 = Possible operation modes: - (NET/GROSS): by closing this input for no more than one second, it’s making an operation of SEMI-AUTOMATIC TARE and the display will show the net weight. To display the gross weight again, hold the NET/GROSS input closed for 3 seconds. -
Page 25: Semi-Automatic Tare (Net/Gross)
SEMI-AUTOMATIC TARE (NET/GROSS) THE SEMI-AUTOMATIC TARE OPERATION IS LOST UPON INSTRUMENT POWER- OFF. To perform a net operation (SEMI-AUTOMATIC TARE), close the NET/GROSS input or press the TARE key for less than 3 seconds. The instrument displays the net weight (just set to zero) and the NET LED lights up. -
Page 26: 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 ENTER. -
Page 27: Peak
PEAK : the peak function is run only via input (default); : the peak function is also run via the START/STOP key. By keeping the PEAK input closed or pressing the START/STOP key (if enabled), the maximum weight value reached remains displayed. By opening the input or keeping the START/STOP key (if enabled) pressed for 3 seconds, the current weight is displayed. - Page 28 - : set the weight value for which you wish to obtain the maximum analog output value; it must correspond to the value set in the PLC program (default: calibration full scale). E.g.: if I am using a 4÷20 mA output and in the PLC program I wish to have 20 mA = 8000 kg, I will set the parameter to 8000.

Page 32: Weight Reading Via Serial Port
WEIGHT READING VIA SERIAL PORT Overview: By transmitting instrument, it means the one connected to the load cell. By receiving instrument, it means the one which receives the weight via serial port. This function allows the instrument to read the weight by another instrument (transmitting instrument) rather than by a load cell, via the RS485 or RS232 serial port. -
