4 Confirm safety prompt with "Yes". Span gas feeding is performed automatically. The
span gas concentration is corrected automatically.
5 The MCS100E HW switches automatically to measuring mode after span gas feeding
has finished.
If you make a mistake when setting the zero or span gas concentrations, the
measured values will be wrong.
b
Before setting the span gas concentration, make sure that the measured
values have leveled out safely (values are stable). This takes 5 ... 15 min-
utes (longer in unfavorable cases) depending on the span gas.
b
Leave the judgment as to whether the "span gas has leveled out" and the
"setting of the span gas concentration" to a trained skilled person.
