Power Disruptions
When electrical power is restored following a power disruption, the 3M™ Attest™
Mini Auto-reader 490M checks the heater block temperature�
• A C1 caution code is displayed under all unoccupied incubation wells if the
temperature is below specification� The C1 caution code will clear when the
temperature reaches specification (60�0ºC +/- 2�0ºC)�
• For any incubating BIs for which the result was determined prior to the power
disruption, the result is displayed when power is restored provided the BI remains
in the well�
• For any incubating BIs for which the result was not determined prior to the power
disruption:
If the heater block temperature is within specification, readings resume as
O
indicated by the remaining incubation time under the BIs on the Display�
After short power disruptions, if the heater block temperature is above 50°C,
O
but not within specification, a C3 caution code is displayed under affected
wells and readings are not taken� Readings resume, as indicated by the
remaining incubation time on the Display, when the temperature reaches
specification�
If the heater block temperature is below 50°C, the E5 error code is displayed
O
below affected BIs� A result will not be determined, and the load/sterilizer
should be tested with a new BI per facility protocol�
