°C above the set

point temperature you will be using during your application or process, or 5

°C above the hottest

temperature of your heating profile.

Note: If this is the first use of the oven, set the Over Temperature Limit to 325

°C to prepare for

the Burn In procedure. This helps ensures the OTL system will not interfere with the Burn
In procedure.
