6.6 Fault conditions
During normal operation, the instrument carries out a continuous self-test procedure. If
operation is satisfactory, the ‘Good/OK’ status indicator will be on, blinking off momentarily
every few seconds.
1) If there are no indicator lamps lit on the
O2NE+™/Safe-Ox+™, check that power is
connected and that the fuses are OK.
2) If the 'Good/OK' indicator is off, and the alarm indications are believed to be incorrect,
carry out a full calibration. If this fails to correct the problem contact your qualified
service engineer.
A summary of the indicator lamps and buzzer operations is shown in the following tables.
