Register Manager Overview
Temperature History Graph
Temperature Limits and Alert/Therm2, Addr/Therm Outputs
The Register Manager application (RegMan) initially displays the main Help screen, where detailed
description of the application’s features may be found. The Help screens can be displayed at any time
by selecting Help from the menubar or pressing the ? button on the toolbar. RegMan enables the user
to display temperature readings, set temperature limits and read/write configuration register values.
To open a Temperature History Graph window, select Plot -> Temperature History Plot from the
menubar. The history plot continuously updates the temperature reported by the temp sensor. There
are several display options, including which temperatures to display (internal, external, external2 for
EMC1033 only), whether limits should be displayed, and if so, for which temp sensor. See a typical
Temperature History Graph in
The high and low limits are displayed as dashed lines, initially with values set in the EMC1002.ini file.
(or EMC1033.ini) These limits may be changed either in the register manager or by dragging the line
on the history plot. If any of the Temp High or Temp Low Limits are exceeded, the
will assert. If the Ext THERM Limit or the Local THERM Limit are exceeded, the
