Single channel digital meter properties

The single channel digital meter displays the current value of the selected channel.

Navigate in a properties dialog using a mouse pointer, keyboard Tab, up-arrow or down-arrow key (not a 10-key pad up-arrow or down-arrow key). Mouse point or Tab between property controls. Use the mouse, up-arrow or down-arrow keys to scroll among options. Click the mouse, Tab or Enter to select an option.

In the digital meter, the background color shows the state of the value.

  • White: A value is within warning and alarm thresholds, or there are no warning or alarm thresholds.
  • Magenta: No suitable connector is found, and a series of "+" characters show overflow.
  • Yellow: A min (minimum) or max (maximum) warning threshold is exceeded.
  • Red: A min or max alarm threshold is exceeded.

Warning and alarm thresholds are set in Test Configuration Edit channel dialogs or in the Test control Digital meter chart Properties dialog.
