Tips of configuring
cfgCO
2
SensorOffset:
1. There must be an interval
of 3 minutes between the
two times calibrations of
CO
2
written into TR50, and
less than this interval
writing operation will cause
failure.
2. TR50 can only accept the
CO
2
sensor offset value
which meets requirement
that CO
2
sensor reading +
offset value > 400 ppm
