BB-Fab BB-EP | 2018-07-17 | East Pond Battery Bank | Upgrade | East Pond Battery Bank | I turned off all the solar power and removed the four remaining size 27 batteries. These batteries were from Mayberry and were about seven years old. I replaced them with five brand new (July 2018 tags) size 31 Duracell deep cycle batteries. These are part number SLI31MDC and have a capacity of 105Ah. Size 27 are rated at 90Ah, so about the same capacity as six size 27s. After the swap the solar panels were feeding the batteries 20A. |

LI-6400 PSC-2474 | 2018-07-16 | Lab none | Calibration | Lab none | Elke Eichelmann & Katrina Cone
We borrowed this LI-6400 from the Silver lab and they had not zeroed and spanned it for about 10 years. We checked the zero with the chemicals and they were a little off, so we set the zero and the span using cal gas and a dewpoint generator. Considering how long this analyzer had not been calibrated the settings were actually pretty good. But it also hadn't been used for most of that time. Then we zeroed and spanned: Zero: Checked using chemicals: CO2_S: 15.2 CO2_R: 7.8 H2O_S: 5.7 H2O_R: 5.7 Set zero using cal gas (zero air): Before: CO2_S:16.8 CO2_R: 6.82 H2O_S: 0.32 H2O_R: 0.282 After: *All fluctuating around zero. Span with 408.97ppm cal gas: Before: CO2_R: 404.4 CO2_S: 404.8 After: *Fluctuating around 409 Span with 16.0C dew point: Before: H2O_R: 15.06C H2O_S:15.02C After: *Fluctuating between 15.99 and 16.01 |
LI-6400 PSC-0785 | 2018-07-16 | Lab none | Calibration | Lab none | Elke Eichelmann & Katrina Cone The 6400 had not been zeroed and spanned for a while. We checked the zero with the chemicals and they were very off, so we set the zero and the span using cal gas and dewpoint generator. Then I zeroed and spanned: Zero: Chemicals: CO2_S: 34.0 CO2_R: 25.4 H2O_S: 13.7 H2O_R: 14.1 Cal Gas (zero air): Before: CO2_S:41.0 CO2_R: 24.3 H2O_S: 3.5 H2O_R: 2.3 After: *All fluctuating around zero. Span with 408.97ppm cal gas: Before: CO2_R: 399.9 CO2_S: 397.1 After: *Fluctuating around 409 Span with 16.0C dew point: Before: H2O_R: 14.69C H2O_S:13.23C After: H2O_R: 16.01C H2O_S: 15.99C **Note: we had to override the maximum slope parameter for the H2O_S to be able to set the slope above 1.100 and to set the correct dewpoint. 'Shift' + 'J' will allow you to override the maximum slope. |
