Check that the Calib zero -value for N
2
O is less than 61000.
If the value exceeds the limit, it indicates bad contamination in the ACX measuring
chamber. The measuring chamber can be cleaned according to the special cleaning
instructions found in the chapter Cleaning the measuring chamber of ACX measuring unit.
However, if cleaning does not help, the whole ACX measuring unit should be exchanged.
NOTE: If the ACX measuring chamber was cleaned or the unit was replaced, then also the
tubing between the D-fend and the ACX measuring unit, including the zero valve, should be
replaced. The mentioned parts should not be cleaned.
NOTE: With monitor software S-___95 and S-___96 the
Calib zero
-value for N
2
O is always
shown as a negative value. The correct value can be calculated by adding the shown value
to the value 65536.

Check the zero valve.
Feed calibration gas into the sampling line and check that the gas readings in the service
menu correspond with the gas values on the calibration gas bottle. Keep feeding gas and
activate the zero valve from the menu. The O
2
reading should drop back near 21 %, the
other gas readings near 0 %. If the readings did not drop, replace the zero valve.
