This menu shows the current range number and range limits.

The Help structure is intended to be an on- line "tutorial," context-sensitive and topic- interconnected, so that the user can practi- cally operate NGA2000 without the need of an instruction manual.

A typical help menu:

Zero/Span calibration help

This allows manual control of the zero and span. Flow zero gas, and make sure the zero gas value is right;

Press the zero key to make the analyzer zero.

Or select Factors and individually adjust the reading on each range. In this way you can make the analyzer read what you want.

Do the same with span gas. If the zero was not a real zero, the span action will change the zero reading>

Set cal gas values in the Calibration gas list screen.
