The FST is designed to perform repeat Quick Screen Tests while in the Road Block
Testing Mode. After the result is displayed the instrument will go into a low power
mode for two minutes. This mode is indicated by a dash slowly moving across the top
of the display.
Once in the low power mode there are three possible events that can change the
instrument's mode of operation:
First, no buttons are pressed during the two-minute low power mode and the
instrument automatically powers
the instrument to a standard testing sequence and if the operator wants to perform
another Quick Screen Test they must go through the menu selection process
again.
A second option is that the operator presses the
OFF
instrument prior to the end of the two-minute low power timer. Again, the
instrument will be in the standard direct sample mode if powered
occurs.
Finally, if the ON button is pressed while the instrument is in the low power
mode, the instrument will quickly return to the Quick Screen Test Mode.
The unit will momentarily display rbL indicating you are conducting a test in the
BLOCK TESTING
mode.
With the icon of a persons head flashing and bLo displayed, the instrument is ready to
perform another Quick Test. (Always use a clean, unused mouthpiece from a sealed
bag). Using this feature allows an operator to perform repeat Quick Test Samples
with minimal delay between tests.
After the result is displayed the instrument will display the temperature followed
by rbL and then bLo indicating it is ready to accept another sample.
(The Quick Screen Test Mode test sequence is approximately 17 – 20 seconds
from the time the subject blows, the instrument displays the result, and it cycles
through the sequence to allow another sample (subject blows, result displayed,
temperature displayed followed by rbL and then bLo).
