UPDATE: Calibration not possible and target value has shifted.

UPDATE: After a few weeks of use and a very informative calibration, the calibration has changed, with outside readings around the 860 (instead of the 405-430 I got when it was new). Since I can't start the calibration mode after following the instructions, I can't fix it. It was fun while it lasted, but I encourage you to buy another one. ALT: Looks like it works by going from room to room and outside. But I can't enter the calibration mode I want to use. The instructions say to press the a and b buttons together to start the calibration and the 200 second countdown, but nothing happens. Anyone have a calibration? Thanks very much!

Pros

CALIBRATION AVAILABLE: The NDIR CO2 sensor supports easy calibration. Press and hold the AB button on the back for 200 seconds, the product will complete auto calibration and the data will return to the original setting value. To ensure the accuracy of the sensor, be sure to place it in a ventilated place (indoor or outdoor) before first use or after long-term storage of at least 6 hours.
