DESCRIPTION
Changes the Internal Data Acquisition System (DAS)
HOLDOFF timer:
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.
Selects the gas measurement mode in which the instrument
is to operate. NO only, NO only or NO
x
simultaneously.
Selects which gas measurement is displayed when the
STABIL test function is selected
Enables or disables the Temperature and Pressure
Compensation (TPC) feature (Section 13.9.2).
Dynamic zero automatically adjusts offset and slope of the
NO and NO response when performing a zero point
X
calibration during an AutoCal (see Section 9.5).
Dynamic span automatically adjusts the offsets and slopes of
the NO and NO response when performing a span point
x
calibration during an AutoCal (see Section 9.5).
Sets the internal span gas generator's permeation tube oven
temperature. Changing this temperature will impact the NO
permeation rate (Section 3.3.2.5).
Sets the number of significant digits to the right of the decimal
point display of concentration and stability values.
Adjusts the speed of the analyzer's clock. Choose + sign if
the clock is too slow; choose - sign if the clock is too fast.
Allows turning ON and OFF the ability to span the analyzer
with NO , in which case the instrument acts as if NO and NO
2
are spanned, even though it is supplied with NO
The NO concentration is then zero by default.

Resets the service timer. Pressing OFF turns the setting to
ON. ENTR resets the timer to 0 and returns the setting to OFF.
Displays number of hours since last service (since
SERVICE_CLEAR was reset).
Sets the number of hours between service reminders.
There is a 2-sec latency period between when a VARS value is changed and the
new value is stored into the analyzer's memory. DO NOT turn the analyzer off
during this period or the new setting will be lost.
