Reaction Block Temp Stabilising
This message is displayed at startup and remains until the reaction
block temperature has stabilized to within 2 ºC (3.6 ºF) of the
programmed control temperature. If the message is still displayed
after 15 minutes:
1.
Check that the sample and ambient temperatures are within
the quoted limits.
2.
Check the 'Heater' value displayed on the 'Measurement
Status' page within 'Diagnostic Information' – see
Section 12.3, page 59.
If the temperature is low, check the heater LED on the main board is
lit. If it is not, contact your local ABB representative.

Reaction Block Temp. High / Low
>2 °C (3.6 °F) but <20 °C (36 °F) above or below
The measured temperature is more than 2 °C (3.6 °F) but less
than 20 °C (36 °F) above or below the programmed control
temperature.
1.
Check that both the sample and ambient temperature are
within the quoted limits.
2.
If the error persists, contact your local ABB representative.

All calibrations
and cleans
Excessive Zero Offset
The zero offset parameter generated at the last zero calibration is
outside of the alarm limits. A system clean is automatically initiated
and another zero calibration is performed.
If the message is displayed after the second zero calibration:
1.
Check the 'Audit Log' to see if a baseline calibration was
carried out after the reagents were replaced. If not, carry out
a baseline calibration.
2.
At the 'Calibration and Maintenance' level, select 'Manual
Test Settings', 'Test Valves' and energize the 'Zero Cal.' valve
(set the parameter to 'On'). Check that the 'Zero Cal.' LED on
the main board is lit and that there is an audible click when
the valve energizes.

Scheduled Zero Cal. Missed
The scheduled zero calibration has been missed due to either a
manual operation being performed or an out-of-service condition.
The next calibration due date is updated automatically.
The next calibration is performed at the correct date and time
if the analyzer is in service
Solution Replacement
The analyzer is shut down while solution is replaced.
