Manual Cal Gas Time Out- Range is 1 minute to 240 minutes, the maximum time in minutes that
a cal gas valve can remain open. A timer starts when the cal gas is opened. The
software will automatically close the valve if the time specified is exceeded.
System Response Time- Range is 15 seconds to 600 seconds in 5 second increments, the amount
of time required for the measurement system to display 95% of a step change in
gas concentration on the data recorder. The System Response Time cannot be
shorter than the Direct Time. The System Response Time is adjusted
automatically when the Direct Response Time is adjusted to greater than the
System Response Time.
Direct Response Time- Range = 15 seconds to 600 seconds in 5 second increments, the time
period set by the operator to allow the automatic gas sequence to inject any cal
gas directly into the analyzer train. This function should be set to a time period
equal to the time required by the slowest analyzer on line in the train to reach
steady state during direct calibration.
Long Response Time- Range is 15 seconds to 600 seconds in 5 second increments, this is a
special response time for exceptionally slow responding analyzers to reach a
steady state reading during calibrations. Used as a mechanism to remove the
necessity to lengthen the system response time for all analyzers to accommodate a
small number of very slow analyzers. The Long Response Time cannot be shorter
than the System Response Time. The Long Response Time is adjusted
automatically when the System Response Time is adjusted to greater than the
Long Response Time.
Last Test Sequence Run- Range is 1 to 12 runs, this number is set by the operator to be equal to
the number of runs he intends to collect data from in the full Automatic mode.
Method 25a CE Gas Path – Sets the calibration path for the direct cal of the THC analyzer.
Gas Divider Control Valve- Range is Valve #1 to Valve #14. The valve is opened to flow gas
when the calibration sequence calls for any divided gas.
There is only an ‘Exit’ button on the screen. The ‘Exit’ button closes the ‘Program Set Up’
screen. The “X” on the screen will also close the screen
When the screen closes the information will be compared to the current configuration
information stored on the disk drive. If there are any differences the program will prompt to save
or discard changes.
