| 1 | SRRL BMS | PY1726 | Global 90-North LI-200 | 07/11/2006 | 13:34:00 | 07/14/2006 | 13:24:00 | The PY1726 instrument which was just calibrated in BORCAL 2006-02, was reading about 1.27 times too high. The calibration history shows a continous decline in response from 15 µV/W/m^2 in 1998 to 9.7 for 2006. There may be a problem with the instrument, so it was removed and replaced temporarily with PY1724. Another instrument will be calibrated in BORCAL 2006-04 which will serve as the replacement. |
