Vars are software variables that define operational parameters automatically set by the
instrument's firmware, and are user-adjustable through this menu. Access the menu to see
the list of variables; select a variable to view its description; touch the Edit button to change
its setting(s).

NOTE: This list includes several of the most common Vars; selecting any Var in the NumaView™ software interface
will display its description in the information field to its right. Depending on configuration, some, all, or more
of these variables appear in your instrument's Vars menu.

Sets the number of significant digits to the right of the decimal point display
of concentration and stability values. ("PRIGAS" = primary gas with two or
more other gases; "SECGAS" = secondary gas)
Enable or disable Daylight Savings Time (also see
Setup>Instrument>Date/Time Settings)
Sets the instrument to compensate for diluted sample gas, such as in
continuous emission monitoring (CEM) where the quality of gas in a smoke
stack is being tested and the sampling method used to remove the gas from
the stack dilutes the gas. Once the degree of dilution is known, this feature
allows the user to add an appropriate scaling factor to the analyzer's NO, NO2
and NOx concentration calculations so that the undiluted values for
measurement range and concentration are shown on the instrument's front
panel display and reported via the instrument's various outputs.
1. Set the appropriate units of measure (Setup>Vars>User Units).
2. Select the reporting range mode (Setup>Vars>Range Mode) and set the
reporting range upper limit (Setup>Analog Output). Ensure that the
upper span limit entered for the reporting range is the maximum
expected concentration of the undiluted gas.
3. Set the dilution factor as a gain, e.g., a value of 20 means 20 parts
diluent and 1 part sample gas (Setup>Vars>Dilution Factor).
4. Calibrate the analyzer; ensure that the calibration span gas is either
supplied through the same dilution system as the sample gas or has an
appropriately lower actual concentration.
Dynamic zero automatically adjusts offset and slope of the NO and NO
response when performing a zero point calibration during an AutoCal (Section
4.3).
Dynamic span automatically adjusts the offsets and slopes of the NO and NO
response when performing a span point calibration during an AutoCal (Section
4.3).
Set instrument to continue sampling, while ignoring calibration, diagnostic,
and reset instrument commands. This feature is of particular use for
instruments connected to Multidrop (2.3.1.8) or Hessen protocol networks.
