Auto-Tuning Screen -
From the Utilities screen (Fig. 16), select the “Auto-Tuning” button and
the screen depicted below will open. From Auto-Tune the operator can:
•
Set the auto-tune temperature values
•
Set the air flow rate
NOTE:
The maximum allowable air temperature must always be greater than the desired
setpoint, and the minimum allowable air temperature must always be less than the desired
setpoint. In general, the wider the allowable temperature range, the better the resulting loop
performance and temperature transition rate of the device under test (DUT).
