38 KICstart User Manual
Graph Controller
The Graph Controller allows the user to modify the view of the KICstart-profile graph. To open the Graph
Controller, Left-click on the TC column header in the Statistics table or Double-Left –click, anywhere just
outside the profile graph.
Auto Scale – The Auto Scale feature will automatically adjust the X, and Y axis scales to fit all of the data
in the profile graph. When the Auto Scale feature is disabled, the user must manually input the minimum
and maximum scale settings for the X, and Y axis scale of the profile graph.
Selecting Thermocouples to View
The TCs section is a list of the thermocouples used for the profile. By selecting All you are selecting that
all the thermocouples used for the original profile will be displayed on the profile graph. In the event that
you wish to view the profile without a particular or multiple thermocouples, you can deselect individual
thermocouples, or deselect the All check box, and choose only the thermocouples you wish to view.
Deselecting Thermocouples
If a thermocouple has become disconnected during the profile, the profile results may be affected to due
above normal peak temperatures and such. This situation may cause the profile PWI value to be artificially
inflated due to bad data. In the event a single or multiple thermocouples become disconnected from the
product during the profile, you can deselect the affected thermocouple(s). The KICstart software will
recalculate the PWI, and update the profile statistics based on the remaining thermocouples selected. You
must select at least one product thermocouple.
Grid – Enables/disables the view of
the X, and Y-Axis scales.
Reference Lines – Enables the view
of Reference Lines displayed on the
profile graph. These lines represent
any temperatures referenced in the
selected Process Window.
Zone Lines – Enables the view for
the oven zone lines on the profile
graph.
Distance From Air TC – Displays
the Distance from the Air TC for each
thermocouple. You can edit these
values. These values were originally
entered before the Profile start.
Wave TC – Distance from Air TC to
each Wave TC.
Distance Between Last Preheat and Wave – This is the distance form the main wave to the last preheat
zone. You can edit this if necessary. This value was originally entered by the user in the Entering Oven
Recipe screen.
