6.3.5 Suppressing gas backgrounds with "ZERO" functions
Unwanted sample gases can be suppressed with ZERO. If ZERO is enabled, the
currently measured leak rate value will be interpreted as carrier gas and subtracted
from all subsequently measured values. The background value suppressed by ZERO
is adjusted automatically if the background changes inside the device. The
background value is automatically adjusted depending on the set ZERO time, except
for filter setting I•CAL, see "Measurement result display with signal filters [
69]".
