Quick update. The latest beta of Calman 4.6 Build 347 fixes the errors I saw previously on the Jeti 1201 firmware version 1.84. Readings are working fine. There is no sync option on the 1201 and for LLH there are options Auto (single), Auto (3 AVG), Auto (5 AVG), 1sec and 2 sec. All return readings. In case anyone else uses the 1201 and Calman. Chromapure worked all along.
