1.3.1 Default Factory Calibration The instrument is shipped with the following default calibration settings: • Capacity – 10,000 kg • Load cell sensitivity – 2.000 mV/V • Division – 1 1.3.2 Theoretical Calibration Use the quick setup menu (Figure 1-3 on page 5 steps 1,2,3, and 4) to perform a theoretical calibration.
Installation Rice Lake Weighing Systems recommends the instrument and the platform (transducer) be installed on a flat level surface, that is stable and vibration free. Location Selection IMPORTANT The following should be considered when selecting a location for the equipment:...
Grounding the System For proper grounding and optimal functioning of the system, it is necessary to create a single point ground in proximity of the instrument on which to connect the ground of the instrument connected cables. Connect the ground point of the instrument, load cells and weighing structure directly to the ground bar of the electric panel or to a grounding pole.
Connection to the Load Cell After proper grounding of the platform and the load cell, connect the shielded cable from the load cell to the instrument ground. See Figure 1-1 on page The load cell terminal board of the instrument may be connected to the 6-wire load cell; 4-wire load cell must jumper sense to the excitation.
Input/Output Wiring Figure 2-4. Input/Output Wiring The maximum power of the outputs 48 Vac 0,15 A max (or 60 Vdc 0,15 A max), the maximum voltage applicable to the inputs is between 12 and 24 Vdc with current from minimum 5 mA to maximum 20 mA. Installation...
Operation Basic Operation The instrument must be powered with stabilized voltage at 12 VDC or 24 VDC supplied from an AC/DC external charger (not included) which should be connected to appropriately rated AC main voltage. To power the instrument, connect the two power supply cables to the appropriate terminal board (Figure 1-1 on page 3) on the side or the back of the instrument.

Cancel a Tare A tare value can be manually canceled in multiple ways: • Unload the scale and press • Press without unloading the scale • Enter a manual tare equal to zero Locked or Unlocked Tare When a tare value is entered manually, automatically or from storage, the tare value displays with a negative sign when the scale is unloaded.
Tare Function Limitations It is possible to limit the tare functions by setting in the step . See Table 4-4 on page 35. The tare operations will have the following specifications: Scale Capacity Function (no remote display for the visualization of the tare) (remote display for the visualization of the tare) <220 lb All tare functions are disabled •...
Multi-Range Function The multi-range function allows for subdividing the scale capacity in two, each up to 3000 divisions. Example: with a 10 kg cell platform it is possible to approve the weighing system with: Single range: 6 kg capacity and 2 g division (3000 div.) Dual range: 6/3 kg capacity and 2/1 g division (3000 + 3000 div.) Multi-range functioning is indicated by illumination of the relative LED identifying the operating range;...
