 When the system is locked (as defined by the user in the CH X > Settings > Limits screen) the Error window will display ∆T with a <color black/green>green</color> background.  As the system approaches lock, it will display ∆T on a <color black/yellow>yellow</color> background.
 ==== Channel Detail Screen ====
-You can set how individual channels behave in the Channel Detail screen.  To enter a Channel Detail screen from the Home screen, touch the CH button for the appropriate channel (<imgref home_scr>). <imgref detail_scr> shows the CH 1 Detail screen.  From this screen, you can change T<sub>set</sub>, and initiate temperature control as from the Home screen.  You can also visually monitor the performance of the loop.  The graph in the lower right of the screen displays ∆T (T<sub>act</sub> - T<sub>set</sub>) on a rolling basis.  The yellow dashed lines indicate the user-defined "lock range."  In <imgref detail_scr>, the lock range is set to ±3 mK.  If ∆T is outside of this range, the Error field will change from green to yellow.\\

-You can also set the various parameters for how the loop will behave.
+  * Change the speed of the rolling display: touch the {{slice:graph_scale_x.gif}} button and select from 1 to 20 s/div.

+  * Change the scale of the vertical axis: touch the {{slice:graph_scale_y.gif}} button and select from 1 mK/div to 10 K/div.
+  * Pause and restart the rolling screen: touch the {{slice:graph_pause.gif}} button.
+  * Turn on & off cursors on the graph: touch the {{slice:cursors.gif}} button.  It is possible to drag the cursors across the display of ∆T to measure an oscillation period.  This function will be helpful be helpful when tuning the loop parameters to your plant.
+=== Display of Transducer Current, Voltage, and Power ===
+As shown in <imgref detail_scr>, the current being delivered to the transducer is displayed in the blue box on the right margin labeled Current [A].  If you touch the blue box, the box will rotate through displaying current through, voltage across, and power delivered to the transducer.
+From this screen, you can also set the various parameters for how the loop will behave.
