Analyzer Zero
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 ZERO again now. Press left arrow key when you are done.

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.
