I have two Thunderbolts that I'm monitoring with Lady Heather. The temperature on the older unit (MFG 2/26/2004) seems to track the environment. The newer one (MFG 11-24-2004) shows 44.750000 °C and only changes in increments of exactly 1°.
Sounds like the newer one has the newer temperature sender chip (DS1620). Briefly, the chip manufacturer changed the innards and the high-resolution display feature. Trimble did not update the Tbolt, but continued to use the newer version of the chip. IIRC, chip revisions prior to E work properly in the Tbolt, while Rev. E (and later, if such exist) do not. The cure is to replace the IC with an older revision chip.
