pre-operational Checks - Final Checks
Check that a
blanking plug
has been securely fitted to the
calibration gas con-
nector
on the probe.
If the blanking plug is not fitted, air leaking into the probe via the
connector can cause measurement errors. In a pressurised flue,
gases venting to atmosphere through the connector could cause cor-
rosion of the test gas tube. In a negative pressure flue, air leakage
can cause high O
2
reading errors.
