Found a problem with the G4 sensors which they should be able to resolve fairly quickly, the plating baths seem to have a problem. The baths have to be temperature controlled, the content of gold has to be monitored, the current applied to attract the gold particles must be exact and constantly monitored, the water must be circulated at the correct pump rate, the baths should be cleaned on a schedule, the parts to be plated must be cleaned before insertion into the gold bath and the timing must be verified for parts and finally a sample should be tested to verify that the baths are working correctly. If you are not meticulous when doing that job, then you will screw up the whole process and based on what I seeing someone is not maintaining the standards that we expect from a medical supplier. I have posted a breakdown on the failure that I have observed with the G4.
