Changes the Internal Data Acquisition System (DAS)
HOLDOFF timer (Section 7.1.11).
No data is stored in the DAS channels during situations
when the software considers the data to be questionable
such as during warm up of just after the instrument returns
from one of its calibration mode to SAMPLE Mode.
Allows the user to set the number of significant digits to the
right of the decimal point display of concentration and stability
values.
Dynamic zero automatically adjusts offset and slope of the
CO response when performing a zero point calibration during
an AutoCal (see Section 9.4).
Dynamic span automatically adjusts the offsets and slopes of
the CO response when performing a slope calibration during
an AutoCal (see Section 9.4).
Adjusts the speed of the analyzer's clock. Choose the +
sign if the clock is too slow, choose the - sign if the clock is
too fast.
Selects which gas measurement is displayed when the STABIL
