5. Using the TIGER Select
Start-up Modes
TIGER Select can start up in either Basic start-up mode or Advanced start-up mode. When the TIGER
Select is first switched on, the instrument will start up in Basic Start-up Mode by default. It may
subsequently be
set up in TigerPC to switch on in Advanced Start-up Mode instead , or to “ask” the
user which mode they require.
Basic Start-up Mode
For efficiency and ease of use, Basic Start-up Mode has been designed to only offer the core
functions for the detection of benzene and other TACs. When using TIGER Select for this specific
purpose, extraneous functionality is not available. Therefore, in Basic Start-up Mode, only the
Standard Running and Tube and Calibration operational modes are available (see below).
Advanced Start-up Mode
Advanced Start-up Mode offers the full functionality of the TIGER Select.
In Advanced Start-up Mode, Standard Running , TAC , and Tube operational modes are available (see
below).
Operational Modes
The TIGER Select has three operational modes: Standard Running Mode, TAC Mode, and Tube Mode.
•
In Standard Running Mode , the display shows a live reading of gas concentration. This mode
will operate using 0.1 ppm sensitivity, unless the ppb sensitivity upgrade has been installed.
In Advanced Start-up Mode, you can select from multiple gases. The chosen gas name is
displayed on the screen.
•
TAC Mode is used to identify the presence of TACs, including benzene. If TACs are detected,
Tube Mode is then activated to determine the specific benzene content. This two-stage
approach avoids using pre-filter tubes unnecessarily. As benzene is a TAC, if there are no
TACs present there is no benzene, and therefore no need to engage Tube Mode.
TACs are also detected in Basic Start-up Mode but TAC Mode cannot be selected from Basic
Start-up Mode.
•
Tube Mode is used to determine the specific benzene content.
Using Basic Mode
The Basic Mode display offers two functions: Tube Mode, and Calibration. Each is selected using one
of the soft keys.
Key A: Tube Mode
Tube Mode is designed to accurately measure the level of benzene gas present using the
Benzene Pre-filter Tube. The initial benzene test has a test time which varies with temperature. This
