Claim 10:
11. A calibration device for a weighing system having a tank, with a plurality of support legs or support brackets for the tank on a solid foundation, a mezzanine floor or a steel structure, the calibration device comprises:
at least one calibration module for applying a force to the tank fixedly connected at an upper end of the calibration module to one of each support leg or support bracket, and fixedly connected at a lower end of the calibration module to the solid foundation, mezzanine floor or steel structure, each calibration module comprising a calibration load cell for converting a force applied from the calibration module into an analog signal;
a calibration terminal for processing the analog signal and displaying, in real time, the applied force from the calibration module; and
at least one analog-to-digital (“A/D”) converter for converting the analog signal into a digital signal, wherein one of the following applies:
for each calibration load cell, a corresponding one of the A/D-converters is located at the calibration terminal for converting the analog signal and providing a digital output signal for processing at the calibration terminal, or
for each calibration load cell, a corresponding one of the A/D-converters is located at the calibration load cell for converting the analog signal and providing a digital output signal for processing at the calibration terminal, or
a smart junction box is provided, having an A/D-converter for each calibration load cell for converting the analog signal received therefrom and providing a digital output signal per calibration load cell for processing at the calibration terminal.
