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 EMC1001. The high

The high and low limits are displayed as dashed lines, initially with values set in the EMC1001.ini file.
These limits may be changed either in the register manager or by dragging the line on the history plot.
