We have a large number of HI 2151/30WC's units, some with C2® load cells and some with older standard load cells. I know we can use the Lbs/Kg's button on the front of the controller to toggle between Lbs and Kg's on the readout of our Hardy controller, but this will not change the units being read into our PLC. I see my options are to re-calibrate all scales in Kg's (my concerns are older standard load cells are rated in Lbs and it will be time consuming to convert approximately 30 scales in one weekend of downtime). The second option I see is leaving the calibration in Lbs and try to do a Lbs to KG conversion in our PLC code (my concerns are trying to get the KG readout on the HI 2151's to match the PLC calculation). Is their any other possible solutions that would be easier to have the HI 2151 return Kg's to the PLC without re-calibrating the scales?
