To the right of the sample gas measuring range, two measuring ranges (1,3) for the test gas
concentrations are displayed. These measuring ranges are used to monitor the gas con-
centration for the automated calibration of zero and span gas. The first measuring range
(1) has a range from -2.0 to +2.0 vol%. The value on top of the green arrow is the zero gas
concentration, in this example 0.0 vol%.
The second measuring range (3), has a range from 19.0 to 24.0 vol%. The span gas concen-
tration value in this example is 21.0 vol%.

Span gas measuring range from 19 to 24 vol%
Note
The measuring range needs to include the value of the test gas
concentration.
Please make sure, to adjust the corresponding measuring range, after
you have changed the test gas concentration. An error will occur,
when the test gas concentration does not fit into the measuring
range.
