An O
span calibration

was attempted and did not
succeed.
If ??? appears in place of
any operator selected
function, it indicates that
the stored value is not
within the expected
range.
The measured value is
more than 1% of full
scale negative.
The measured value is
more than 120% of the
rated full scale of the
instrument.
The measured oxygen
value is more than 1% of
full scale negative.
The measured oxygen
value is more than the
rated full scale of the
oxygen channel.
A calibration failed for
one of the above reasons
and there is no valid data
from a previous
successful calibration.
The digitized oxygen
sensor signal is
significantly out of range.

Most frequently, this is caused by
attempting a full calibration on the
SAMPLE gas. The instrument will
zero calibrate on your sample gas if
requested to do so!
Check SETUP: O2 CAL GAS for
proper O
span gas value.

Impending O
sensor failure. Replace

the O
sensor.
2
Check sample system for leaks.
Re-enter the correct value. If the error is
not caused by a hardware fault,
attempting to change the value will
bring it back within the normal range.
Recalibrate the instrument.
If recalibration does not correct this
error, discontinue using the instrument
and contact LSC.
Recalibrate the instrument.
If recalibration does not correct this
error, discontinue using the instrument
and contact LSC.
Recalibrate the instrument.
Replace the O
sensor.

If the error occurs again, discontinue
use of the instrument and contact LSC.
Recalibrate the instrument.
Replace the O
sensor.

If the error occurs again, discontinue
use of the instrument and contact LSC.
Replace the O
