IMIT
The incubator must be operating at your incubation application temperature and must be stable for at least
1 hour prior to setting the OTL. Each incubator OTL must be set independently in the SMI12.
If the OTL is sporadically activating, you may turn the dial slightly to the right (clockwise).
If the OTL continues activating, check for ambient sources of heat or cold that may be adversely impacting
the unit temperature stability. Check if any powered accessories in the workspace chamber are generating
heat. If you can find no sources of external or internal temperature fluctuations, contact Tech Support or
your distributor for assistance.
End of Procedure
1. Set OTL control to its maximum setting, if not already set to max.
2.
Turn the dial counterclockwise until the red Over Temperature Limit Light illuminates.
3.
Slowly turn the dial clockwise until the OTL Activated light turns off.
•
The Over Temperature Limit is now set approximately 1˚C
above the current incubator air temperature.
4.
Leave the OTL dial set just above the activation point.
Optional:
Turn the dial slightly to the left.
•
This sets the OTL cutoff threshold nearer to the current
incubator air temperature.
