1 | BMS | | Global LI-190 | 05/20/2022 | 00:00:00 | | | The SRRL BMS Global LI-190 Quantum sensor is reading low, most likely due to water contamination into the sensor. It may dry out. |
2 | BMS | Q8432 | Global LI-190 | 09/24/2017 | 00:00:00 | 10/16/2017 | 00:00:00 | The SRRL BMS Global LI-190 Quantum sensor is reading about 25% low, problem unknown at this time, but it is most likely water contamination. Signal returned to normal on 10/16/2017, it may have dried out. |
3 | BMS | | Global LI-190 | 04/27/2015 | 00:00:00 | | | The SRRL BMS Global LI-190 Quantum sensor is reading about 15% low, problem unknown at this time. |
4 | BMS | Q8435 | Global LI-190 | 04/03/2008 | 00:00:00 | 04/23/2008 | 12:11:00 | The SRRL BMS Global LI-190 Quantum sensor went faulty on April 3, 2008. The bad sensor (S/N Q8435) was replaced with a spare sensor (S/N Q8432). Sensor started reading 10-20% low starting April 3, was calibrated on April 14, then seemed to shift back to normal, which caused the sensor to read 10-20% high using the new cal factor. |
