The Analyzer Module will not allow the user to increase the upper limit of a range
beyond the "maximum range" software setting. To change the "maximum range"
value, select the following from the Main Menu: Technical Configuration Menu,
Service Menu, Manufacturing Data, Analyzer Manufacturing Data. Select Maximum
Range, and use the arrow keys to scroll the indicated value. The same applies for
"minimum range" setting.

Analyzer Span
Are you sure?
You must have zero gas flowing
through the analyzer.
This control does NOT control any
auto-cal. Module bound to this
analyzer!
If you are sure, press SPAN again now.
Press left arrow key when you are
done.

Measurement range number: 1
Range upper limit: 10 ppm
Range and functional control: LOCAL
Zero gas concentration: 0 ppm

Ranges with valid calibration: 1&2
Calibration status: Ready

Status: Ready
Expert and Technical menus follow in
succeeding flow charts.
If it won’t calibrate...
Check that you are flowing the correct gas, and
the gas concentration is what it is supposed to be.
Make sure that the reading is stable before
starting. If you have changed the range fullscale
value or any linearizer coefficients, or enabled or
disabled it, or done anything else that would affect
how it measures the gas, you may have made it
hard for the analyzer to calibrate. If so, manually
adjust the coefficients until the readings are close
to correct, and try again.
Analyzer Zero

You must have zero gas flowing
through the analyzer.
