• Use the UP/DOWN keys to set the hour (24
hour clock format). When correct press 'OK'
• Use the UP/DOWN keys to set the minutes.
When correct press 'OK' to return to the
Setup menu

required language: English, French, Spanish
and Mandarin
• When correct press 'OK'
Check Calibration
Validate the temperature calibration of the
incubator for performance review. The
temperature is controlled by two laser-trimmed
thermistors which are supplied factory
calibrated and designed for long term stability.
There is no natural drift in the calibration of
the incubator over time and hence no need
to field-adjust the calibration.
Using two identical thermistors located
separately provides a dual validation approach
to performance monitoring. It is possible but
unlikely that either thermistor may be damaged
in normal use but the possibility of both
thermistors being compromised in an identical
manner is almost zero.

The Check Calibration function provides a simple
electronic check that both thermistors are reading
the same temperature as each other within a
specified tolerance. If the comparison is out of
range the display will show Error 107: Validation.
• Highlight 'Check Calibration' and press 'OK'
• The incubator will display 'Calibration
Verified' upon completion
• Press 'Back' to return to the Setup menu
In the unlikely event of failure, return the incubator
to your local service representative for attention,
quoting the serial number shown on the base.
Version
View the software version number for
identification and potential upgrade.
• Highlight 'Version' and press 'OK'
• Note the software version displayed
Resuscitation Period
To improve microbiological analysis performance,
stressed samples should be subjected to a period
of acclimation prior to incubation.
To automatically include a resuscitation period
highlight 'On' and press 'OK'.
Resuscitation periods from 1-4 hours are set
from the Incubation menu when set to 'On'.
If resuscitation is not required highlight 'Off'
and press 'OK'.
