I recently acquired a Bicron Analyst and have been trying to learn more about the unit. I was able to find a tech manual for the radiac but in the description of possible probes it merely lists "various" as acceptable probes. I was considering using a 44-9 and 43-2 probes with the unit. Does anyone see a reason why they would not work effectively with this meter? Any experience with this would be great. I do love the bicron meters but it can be hard to get info on anything other then the micro analyst.
