Description: | The temperature unstable flag or CCN_temp_unstable_flag(time) seems to be set to 1 even when the temperature is stable. This started after the instrument software was upgraded. To check for temperature stability use instead the CCN_dT_TEC3_TEC1_StdDev(time) variable which gives the standard deviation of the 1 second temperature differential between T3 and T1. When this variable is at or below 0.05 C then the temperature can be considered stable. |
