6.6. Setup - Internal Variables (VARS)

The M100E has several-user adjustable software variables, which define certain
operational parameters. Usually, these variables are automatically set by the
instrument's firmware, but can be manually re-defined using the VARS menu. Table 6-5
lists all variables that are available within the 818 password protected level.

Changes the internal data acquisition system (iDAS)
hold-off time, which is the duration when data are
not stored in the iDAS because the software
considers the data to be questionable. That is the
case during warm-up or just after the instrument
returns from one of its calibration modes to SAMPLE
mode. DAS_HOLD_OFF can be disabled entirely in
each iDAS channel.
Enables or disables the temperature and pressure
compensation (TPC) feature (Section 10.7.3).
Sets the sample chamber temperature. Increasing or
decreasing this temperature will increase or decrease
the rate at which SO
10.1.1).
Do not adjust this setting unless under the direction
of T-API customer service personnel.
Sets the IZS option temperature. Increasing or
decreasing this temperature will increase or decrease
the permeation rate of the IZS source (Section
5.4.2).
Dynamic zero automatically adjusts offset and slope
of the SO response when performing a zero point
2
calibration during an AutoCal (Chapter 7).
Dynamic span automatically adjusts slope and slope
of the SO response when performing a zero point
2
calibration during an AutoCal (Chapter 7).
Note that the DYN_ZERO and DYN_SPAN features
are not allowed for applications requiring EPA
equivalency.
Allows the user to set 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 the
+ sign if the clock is too slow, choose the - sign if
the clock is too fast.
