Sensor had been running for 5 days, since 10/3 when it had a huge H2O zero offset when analyzing zero gas. I'm not sure why it was reading weird values on 10/3, but the numbers seem ok today, consistent with a chemical swap. In the future, we should let the sensor run for 1 week after swapping internal chemicals, rather than calibrating after only 24 hours. |
