2. Full/Quick Start Mode
Full Start purges the sample, zero, calibrator and span gas lines
before the analyzer is used for the first time. Quick Start purges the
sampling line after disconnecting and connecting the gas inlet lines,
or after the unit has been turned off momentarily. Use Quick Start
after the analyzer has been running on a daily basis and the sample/
span gas needs to be disconnected/connected. (To disconnect/
connect gas lines, the analyzer must be in Stand-by mode. See
Stand-by mode menu information later in this chapter.)
3. Analyze mode (Calibration/Setup/Range/Stdby)
Analyze mode is the normal mode of sample gas analysis. During
normal analysis of the sample gas, other modes available from the
Analyze mode are:
a. Calibration mode:
Allows you to set the analyzer zero and span.
b. Setup mode:
Initializes the alarms, modem, allows you to schedule
Autospan and Autozero at pre-determined intervals, select
internal or external zero gas, positive O

reading display
option, slope of zero/span auto settling and degree of filter-
ing of signal.
c. Range:
Allows you to set the range manually or use the AutoRang-
ing feature.
d. Stand-by (shutdown) mode:
Keeps the analyzer ready for operation when:
• no gas is flowing through the system
• the sample/span gas line is being connected or disconnected
• proceeding through normal shutdown of the analyzer.
4. High Current Output mode:
Closes all valves to protect the Ultra Trace sensor and preserve the
oxygen scrubber when concentrations of oxygen higher than 30
PPM are detected for longer than two minutes. (This mode is
activated only when the analyzer is in the Analyze mode).
Pressing buttons in certain sequences allows you to set modes of
operation. The system’s electronics subsequently operate the correct
valves depending on the options that you choose. The choices are
displayed on the LCD screen and vary depending on the mode.
