A quick continuity check showed that the thermocouple was OK. There are not many of these functioning units left in captivity because it is just too easy to blow up the thermocouple. So, Larry, I recommend that you do what I did, build a ferrite ring current transformer type and put your thermocouple unit back into storage once you have calibrated it! Dick, capitals are normally used for abreviations i.e. RF not rf. Modern practice, at least in letter writing, is to leave out much of the punctuation which used to be used i.e. RF not R.F. 73, Tom G3OLB
