Too many pulses
The 3000S will automatically increase the calibration time when it receives
less than 12 pulses within 5 seconds and decreases calibration time when
receiving more than 999 pulses within 5 seconds.
Calibration is possible only when the 3000S receives 12 to 998 pulses within 2
to 60 seconds.
The system will measure three times the number of pulses and save an
average value.
The calibration time will have an influence on the fan speed response time in
relation to CO
value and duct temperature
