Are there any factors that could cause the
measurement environment temperature
to change drastically? (Close to the
air conditioning blow-off port, heating
appliance, etc.)
Calibrate the span in a room with little
temperature change, where it is not affected
by air conditioning.

If the symptoms are not resolved even after
taking the above actions and confirming
the calibration conditions, the oxygen
sensor membrane may be damaged.
Replace the oxygen sensor with a new part.
(Contact the dealer from which you purchased
the product if the warranty is still valid.)

Sensor warranty term (O
2
)
This message shows the remaining number of
days in the oxygen sensor warranty term.
Check the remaining number of days in the
warranty term.
The following message “Sensor warranty
expired” appears when the warranty has
expired. Prepare to replace the sensor as soon
as possible.
Sensor warranty expired
This message indicates that the oxygen
sensor warranty has expired.
The oxygen sensor cannot be used for
more than one year.
The oxygen sensor can be used past the
warranty term. However, the following “Sensor
life reached” error will occur in time, and
calibration and measurements will not be
possible. Prepare to replace the sensor as
soon as possible.
Sensor life prediction
This message indicates that the oxygen
sensor life is almost reached.
The oxygen sensor’s service life is
approaching.
The sensor can be used for a while after the
message appears, but the oxygen sensor
output has dropped, so calibration will not be
possible in time. Prepare a new oxygen sensor
and replace.
