Display Area
Numeric readout mode is always mode 2. Numeric readout mode assists the service personnel with the troubleshooting of the sensor inputs. The inputs supply information for the gauges in the quad gauge modules. Numeric readout mode more accurately shows the same information that is shown on the gauges in normal mode. The system identifier and numeric value for the system scrolls on the six digit display area. The system identifier identifies the system that is currently shown on the six digit display area. See table 1 for "System Identification" and illustration 2 in order to match the system identifier to the appropriate gauge.

All other gauges in the quad gauge modules are shut off. The gauge needles will move to the far left position. When you enter the numeric readout mode, the six digit display area is showing information for system GA-1. The display momentarily shows the system identifier. The display then shows the value for the corresponding system on the six digit display area. Grounding the service input causes all the systems to scroll on the display. This will show the system identifiers. Removing ground from the service input stops the scrolling, when the desired system is shown. The six digit display area continues to show the system identifier momentarily. The six digit display area then shows the value of the system. The system is now shown on hold. While the system is on hold, the numeric value of the system is continuously updated.
