| LI-610 DPG478B | 2021-03-01 | Lab none | Maintenance | Lab none | The dew point was stuck at about 34C - not dropping to the set point of 20C. I found a crack in the "from cooler" tubing. I replaced this piece of tubing but this didn't solve the problem. There was an air bubble in this piece of tubing and the machine was making an unusual bubbling sound. Refilling the reservoir with DI water immediately change the sound, got rid of the air bubble in the tubing and the dew point began to drop towards the set point. |

| CR1000 23865 | 2021-02-25 | Lab none | Maintenance | Lab none | The internal lithium battery was nearly dead 1.6V. I couldn't find a new one but swapped it for one reading 2.6V instead. Be sure the check the clock when using this logger. |
| CNR4 121038 | 2019-11-17 | Factory none | Calibration | Factory none | Initial calibration by Kipp and Zonen. LW on 2019-11-17: LW_in = 6.83 uV/(W/m2), LW_out = 5.48 uV/(W/m2). SW on 2019-11-15: SW_in = 14.56 uV/(W/m2), SW_out = 14.17 uV/(W/m2) |
| NR01 2420 | 2021-02-18 | Lab none | Repair | Lab none | Over the last week or so I disassembled and cleaned this sensor. I don't see any water damage but I can't get the LW junction board loose as it seems glued to the case. I totally replaced the four wires running between the LW and SW sides. These wires were broken after having been previously broken and spliced. I soldered new wires directly to the junction boards. I collected about two days of data on the window sill with the sensor partially disassembled so that all four sensors could point up together. The relationship between the paired sensors was very tight (r-squared >0.99) - excluding a portion of the LW data that might have been affected by solar heating. LW had a sloped of 1.01 but SW had a slope of 1.20 - new calibration coefficients are probably needed. Today I completely reassembled the sensor and put it out the window on a boom to collect some data to check the assembly. |
