I do have one that my company tossed (if you can believe it) because it was too expensive to maintain and was not being used. Cheaper to get rid of it than keep it in inventory and calibrate it every year... (it's an accountant thing) It was calibrated last year in August and passed everything. The issue is that the RAM battery is due to be replaced about now and it is my understanding that it is A LOT cheaper to replace them before they are dead. So I may need some advice as to what is the best way to do that.
