2.1.2 TN/TNx Channel Calibration Quality

After the TN and TNx channel calibration it is important to check the slopes and offsets to make sure they fall within the acceptable range. The tolerances are different than a typical NOx analyzer primarily because of the performance of the M501NH ammonia converter.

Slopes can vary from 2.0 to 0.7, and should be within 20% of each other with the TNx slope typically smaller than the TN slope.

Offsets should be zero ±250 mV and be within 100mV of each other.

If the slope and offsets are within specifications, proceed on the ammonia channel calibration.
