air stream temperature, based upon this 60/ limit, would not be allowed to
drop to -100/ until the UUT core temperature had reached -40/
The same rules hold true for the high end of the UUT range except that the high
differential limit (F30) is applied at the high limit of the UUT range (F28).
For UUT core temperatures between those limits, a proportional differential limit
is calculated by the C4 based upon the limits specified at the extremes. For
Example:
If the lower UUT limit (F27) is set to -100/ and the the lower differential
limit (F29) is set to 60/, and the upper UUT limit (F28) is set to 200/, and
the upper differential limit (F30) 20/, the differential limit calculated for a
temperature of -25/ would be 50/.
Important: Intelligent 2 Probe Control, like normal control using probe 1 or
probe 2, is constrained by the limits of the controller range and the
chamber/platform operating temperature limits (F25 & F26). If a probe correction
has been implemented for either or both probes (F17 - F24), those adjustments
will be used as well. It is imcumbent upon the user to be certain that they are
aware of these settings and their potential for interaction.
4.3 Using Intelligent 2 Probe Control
Once all of the necessary settings have been made and verified, using Intelligent 2
Probe Control is very easy. To use Intelligent 2 Probe Control, set the probe
number to zero (0). Intelligent 2 Probe Control will be used in any mode, Local,
Program, or Remote, if the probe number = 0.
