OPERATION (CONTINUED)
Temperature Calibration Continued
10. If the temperature readings of the incubator and the reference device still fall outside your
laboratory protocol after three calibration attempts, contact Sheldon Technical Support
for assistance.
a. Three calibration attempts may be required to successfully calibrate units that
are ±2°C or more out of calibration.
End of Procedure
S ET THE O VER T EMPERATURE L IMIT
The incubator temperature must be stable running at your temperature set point for at least one
hour prior to setting the OTL. Perform the following steps to set up the Over Temperature Limit
system for normal use:
End of Procedure
1. If you have not done so already, turn the Set Over Temperature Limit
control dial clockwise to the maximum position. This allows the Set
Temperature control to stabilize.
2. Turn the Over Temperature Limit control dial counterclockwise until the
red Over Temp Limit Activated light illuminates.
3. Slowly turn the Over Temperature Limit control dial clockwise until the
Over Temp Limit Activated light turns off. Stop turning the control.
4. Leave the OTL control slightly above the activation point. This sets the
Over Temperature Limit set to approximately 1 ˚C above the current
temperature set point.
