Zero Correction
The sensor models SE 7*6 ... and SE7*7 ... have a very low zero current.
For trace measurements below 500 ppb, the zero point should be calibrated.
If a zero correction is performed, the sensor should remain for at least 10 to
60 minutes in the calibration medium (media containing CO
2
at least 120 min)
to obtain stable, non-drifting values. During zero correction, a drift check is not
performed.
