Features Of The 3M™ Attest™ Auto-Reader 490H; Information Button - 3M Attest 490H Benutzerhandbuch

With a processed 3M™ Attest™ Biological Indicator, a positive (+) result indicates a
sterilization process failure. Act on any positive test results immediately. Determine the
cause of the positive 3M™ Attest™ Biological Indicator and retest the sterilizer following
current facility policies and procedures.
Optional Visual pH Color Change Result ‑ 3M™ Attest™ Rapid
Readout Biological Indicator 1295
3M™ Attest™ Rapid Readout Biological Indicators 1295 for Vaporized Hydrogen Peroxide
Sterilization may be further incubated for a visual pH color change. Due to the high
sensitivity of the fluorescent result, there is no advantage to continuing to incubate 3M™
Attest™ Rapid Readout Biological Indicators 1295 after the fluorescent result has been
determined and documented. This optional further incubation is not intended for routine
use but may be used for special studies.
In the case of a positive control BI, a yellow color change of the growth media will appear
within 24 hours. Any observation of a yellow color within the vial indicates a positive
result. The pH color change result can be recorded and the BI discarded as soon as the
yellow color is observed.
For processed 3M™ Attest™ Rapid Readout Biological Indicators 1295, the use of a
humidified incubator is recommended to avoid media dry out. If a visual pH color change
result is desired, transfer the processed 1295 BI to a humidified incubator after the
fluorescent result has been determined in the 3M™ Attest™ Auto‑reader 490H. A media
color change from purple to yellow indicates a sterilization process failure. A negative pH
color change result, i.e., media remains purple, can be assessed at 7 days.
Optional Visual pH Color Change Result ‑ 3M™ Attest™ Super Rapid
Readout Biological Indicators
3M™ Attest™ Super Rapid Readout Biological Indicators may be further incubated for
a visual pH color change. This optional further incubation is not intended for routine use
and may be used for special studies. Due to the high sensitivity of the fluorescent result,
there is no advantage to incubating the 3M™ Attest™ Super Rapid Readout Biological
Indicators 1491 and 1492V beyond 24 minutes. After activation and during incubation,
the white Nonwoven Material in the biological indicator will absorb bromocresol purple
indicator, the pH‑sensitive indicator dye in the growth media, and appear blue. In the
case of a positive control BI, a yellow color change of the growth media and/or Nonwoven
Material will appear within 24 hours for 1491BIs and within 48 hours for 1492V BIs. Any
observation of a yellow color within the vial indicates a positive result. In the case of a
processed BI, a media and/or Nonwoven material color change from purple to yellow
indicates a steam sterilization process failure. A negative pH color change result, i.e.
media and Nonwoven Material remain purple/blue, can be assessed at 24 hours for
1491 BIs and at 48 hours for 1492V BIs.
INSTRUCTIONS FOR USE – DISPOSAL
Instrument contains a lithium battery. Dispose of instrument in accordance with federal,
state, and local requirements.
FEATURES OF THE 3M™ ATTEST™ AUTO‑READER 490H
Audible Alarm
An audible alarm will sound, the LCD display backlight will flash, and a (+) symbol will
be displayed on the LCD panel directly under the incubating BI when a positive result is
detected. An alarm will also sound if a 3M™ Attest™ Biological Indicator is removed from
the 3M™ Attest™ Auto‑reader 490H well before a final result has been detected. Data
will be lost if the 3M™ Attest™ Biological Indicator is not replaced in the incubation well
within 10 seconds.
Alarm On/Off
The audible alarm for positive results can be turned off for a particular 3M™ Attest™
Biological Indicator. This is accomplished by pressing the "Buzzer Alarm OFF" button after
the alarm has sounded. This will turn off the alarm for that BI only. Any positive 3M™
Attest™ Biological Indicator results subsequently detected in other wells will result in the
alarm sounding. Removing the 3M™ Attest™ Biological Indicator will reactivate the alarm
for that well. Pressing the "Buzzer Alarm OFF" button will not silence the alarm for error or
caution code alarm warnings. To disable the alarm, see configuration section.
Stackable
To save counter space, 3M™ Attest™ Auto‑readers 490H may be stacked two high.
Information Button
When the Information button is pressed once the 3M™ Attest™ Auto‑reader 490H
displays two lines of text in the LCD Display.
The top row indicates (left to right):
• 3M™ Attest™ Auto‑reader 490H serial number
• 3M™ Attest™ Auto‑reader 490H embedded software version (V X.Y.Z)
• Current date and time.
The bottom row indicates:
• The BI type configuration for wells 1‑10 (i.e., Attest)
Press the information button twice and the 3M™ Attest™ Auto‑reader 490H LCD Display
will present two additional lines of text.
The top row indicates:
• IP address.
The bottom row indicates (left to right):
• Date (YYYY‑MM‑DD) and time that power was supplied to the 3M™ Attest™
Auto‑reader 490H.
Press the information button three times and the 3M™ Attest™ Auto‑reader 490H LCD
display will present the unique Media Access Control (MAC) Address for the device.
Temperature Monitoring
The 3M™ Attest™ Auto‑reader 490H contains an internal temperature self‑diagnostic
program. Should the temperature fall outside the specified range (60ºC +/‑2ºC) an error
code will be displayed. The heater block temperature may be checked by depressing the
Temperature button once.
Easy Configuration
The 3M™ Attest™ Auto‑reader 490H may be configured using either the buttons located
on the front of the unit or using the optional 3M™ Attest™ Auto‑reader 490H Web App.
Optional 3M™ Attest™ Auto‑reader 490H Web App
If desired, the 3M™ Attest™ Auto‑reader 490H may be connected to a PC via an Ethernet
connection for additional capabilities:
• Remotely view current status of BIs in the 3M™ Attest™ Auto‑reader 490H via
networked PC. For full functionality, the use of an HTML5 compliant browser with
JavaScript enabled is required.
• Remotely view and configure 3M™ Attest™ Auto‑reader 490H settings.
• View the last 100 BI records.
• Print out documentation using a local or networked printer and/or save documentation
as an electronic file.*
Note: To access the 3M™ Attest™ Auto‑reader 490H Web App within a secure network,
the PC must have access to the secure network; options include connecting via a network
Ethernet cable, signing in to the facility's wireless network, or connecting via a virtual
private network (VPN).
* Refer to your facility's record keeping policy and procedure.
