named DataView. DataView appears as the main menu on the keyboard display.
DataView has menu item Counter, and submenus PanelTemps, TCTemps and
System Menu. Counter allows selection of one of four values. Each submenu
displays two values from CR800 memory. PanelTemps shows the CR800 wiring-
panel temperature at each scan, and the one-minute sample of panel temperature.
TCTemps displays two thermocouple temperatures.
