| 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. | 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.

| 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 set how individual channels behave in the Channel Detail screen.

| 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. |

| | * 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. |
