Detailed Description

In OPERATE MODE, the 26800 executes USER PROGRAM instructions which may collect sensor data, store records, process data, display results, produce outputs, or communicate via serial ports. When the 26800 is powered up, it automatically enters OPERATE MODE.

Typically, measured data will appear on the display. If multiple sensors are connected, data may appear on more than one screen. There are 8 display screens available. Use +SCREEN and –SCREEN soft-keys to select screen view. SCREEN SCROLL settings or USER PROGRAM instructions may limit the viewable screens to less than 8. Press the NEXT soft-key to cycle through OPERATE MODE options
