<ul><li>Set Bcal chiller temperature to 41 deg F (5 deg C) in preparation for run</li><li>Chiller changed temperature smoothly down from 64 degF. See attached screen shot.</li><li>All RTDs track the change in chiller temperature, except for 2D which seems to have an offset of about 10 degC relative to all the rest. As this is connected in series with an adjacent module, this must be an artifact.</li><li>See a strip chart of TRD 2 and 3 D and all four humidity sensors for this period. </li><li>RTD 2D seems to be tracking the other temperatures but with a 10 degC negative offset.</li></ul>
