By default, this option is not available via either soft key. Assign it to a soft key menu
When selected, all audible and visual alarms are disabled except for the alarm indicator on the
screen. This function may help avoid triggering panic in public places.
Tube Mode
IF THE LEVEL OF BENZENE THROUGH THE PRE-FILTER TUBE EXCEEDS 200 PPM
THE ACCURACY OF THE READING SHOULD BE APPROACHED WITH CAUTION.
READINGS ABOVE 200 PPM ARE STILL DISPLAYED, HOWEVER, THE DISPLAY WILL
FLASH “>200” IN THE BOTTOM LEFT CORNER OF THE SCREEN.
Important
: Benzene Pre-filter Tubes should be used for a single reading and one
STEL test only. ION Science recommends that a new tube is used with each tube
measurement for best accuracy and performance.
The TIGER XTS should not be stored with tubes connected.
Additional Notes
: When using the TIGER XTS to measure higher concentrations of
benzene, the concentrations of other hydrocarbons may also be high, and the
Benzene Pre-filter Tube capacity should be considered:
•
As the pre-filter capacity reaches its limit, the tube will change colour
from bright orange to a green/brown.
•
If the colour changes beyond the ¾ marking, the benzene concentration
may not be accurate.
•
If the colour changes past the ¾ marking (see
A
below), as long as the
benzene reading is below the test limit (e.g. 200 ppm), the result is still
within the environmental compliance.
The working temperature range of the Benzene Pre-filter Tube is between 2°C to
40°C (36°F to 104°F).

Preparing the Benzene Pre-filter Tube
Use the Tube Opener supplied with the instrument:
Remove both ends of the Benzene Pre-filter Tube using the Tube Opener. This is done by inserting
the tube into the Tube Opener and twisting the tube. A slight angle may be required to cut the glass.
