Zero Correction
For trace measurements below 500 ppb, the zero point should be calibrated.
If you want to perform a zero correction, then you should keep the sensor in
the calibration medium (eg, N2 or sulfite solution) until the measured value
has stabilized. This may well take several minutes. After that, you can start the
calibration process.
