Display AreaThe Numeric Readout Mode assists service personnel with information on the Load and Consumption. Also, information for troubleshooting of sensor inputs is provided. The information on Load and Consumption is only shown on the six digit display area. Mode 2 accurately shows information pertaining to the sensors that are being monitored.. The system identifier "PA-X" precedes the value that is shown on the display. Then, the parameter value is shown on the display. To enter Mode 2, hold the "CLEAR/MODE" Switch in the MODE position until "-2" appears on the display. Use the "SCROLL" switch in order to advance the display to the next parameter value. The display will momentarily show the identifier "PA-X". Then, the display will change to the value of the parameter.

The scroll switch causes all of the systems to scroll on the display. The system identifiers are shown. Release the scroll switch when the desired input is shown in order to stop the scrolling. The display continues to show the system identifier. Then, the display changes in order to show the system value. The system is now shown on hold. The value is continuously updated while the display is on hold.
