4.1.1 Controller Display Features
When a sensor is connected and the controller is in measurement mode, the controller automatically identifies the connected sensors and displays associated measurements.
The display will flash on startup, when a sensor error has occurred, and when a sensor is being calibrated.
An active system warning will cause the warning icon (a triangle with an exclamation point inside) to be displayed on the right side of the display. See Figure 13.
