9RANGE: Used to set up three analysis ranges that can be switched automatically with auto-ranging or used as individual fixed ranges.

10STANDBY: Remove power to outputs and displays, but maintain power to internal circuitry.

Any function can be selected at any time. Just scroll through the MAIN MENU with the DOWN/UP control to the appropriate function, and ENTER it. The analyzer will immediately start that function, unless password restrictions have been assigned. (Password assignment is explained further on.)

All of these functions are described in greater detail in the procedures

starting in section 4.3. The VFD screen texts used to illustrate the procedures are reproduced in a Monospaced type style.

4.2.2 Data Entry

4.2.2.1 ENTER

When the item you want from the VFD screen appears between the arrows on the VFD screen, ENTER it using the ESCAPE/ENTER control.

When the selected option is a function or subfunction, ENTER moves to the VFD screen for that function or subfunction.

When the selected option is a modifiable item, the DOWN/UP control can be used to increment or decrement that modifiable item to the value or action you want. Then you ENTER the item.

ENTER then puts you into the next field to continue programming. If the screen is completed, ENTER takes you to the next screen in the process, or if the process is completed, ENTER takes you back to the ANALYZE screen.

4.2.2.2 ESCAPE

If you do not wish to continue a function, you can abort the session with a turn-and-release toward ESCAPE. Escaping a function takes the analyzer back to the previous screen, or to the ANALYZE Function, depend- ing on the function escaped.
