I have a new to me applicator with a ravens unit on it. I have all the cal. numbers entered in the 440 but, the one on the meter. The 440 needs a cal number entered in. What do I need to do to get a cal. number for the meter? Can the meter be run on a tester and re-calibrated? And if so where do I take it or send it?
