Zero/Span Calibration help
This allow manual control of the zero and span. Flow zero gas, and make sure the gas value is correct: press the zero key to make the analyzer zero itself. Or select Edit measurement using zero offset, then scroll the reading with the up and down keys. In this way you can make the analyzer read what you want.
Then do the same with span gas. If the zero was not a real zero, the span action will change the zero reading; the last zero reading shows you what it would have been on the zero gas with the current span.
