We are replacing our obsolete weight controller with a new Hardy controller and want to reuse the same load cells. Our traditional calibration methods are giving us problems when we try to set the span. I think it's because our old unit has 10 volts excitation and the Hardy unit has 5 volts excitation. When we run the mV calibration signal above 15, we get an A/D Conversion Error on our Hardy unit. Do we need to take our old calibration values and divide by 2?
Someone pulled the cable out of our Hardy load cell and I would like to re-connect it myself. Can you send me directions on how to replace the cable? I read the manual and performed the resistance measurements, but the results are outside the maximum tolerances. Can I repair this load cell or do I have to replace it?
Our contractor has installed several load cells upside down, is this a problem? We are also installing some Advantage load point assemblies and would like to know what is the correct orientation?
What are some general load cells application notes that I can use to select the right load cell and protect the load cell during and after installation?
