5) This HOLD/SAMPLING cycle will repeat for 3
total samples. A new PEAK value will be added for
each completed SAMPLE cycle above the timer
field. At the end of the third SAMPLE cycle, the
instrument will return to ON mode and the breath
value display will show the average of the 3 PEAK
sample values as indicated by “AVG” above and to
the right of the numeric display as shown to the right.
Throughout the SAMPLE MODE cycles, the display
can be toggled between a numeric value and a
graphical value by pressing the
RIGHT ARROW
button to show graph display and the
LEFT
ARROW
button to return to numeric display. The
graphical display is shown to the right.
To begin a new SAMPLE MODE cycle for a new patient, press the
ENTER
button from
ON MODE. This will clear the previous AVG reading and the 3 PEAK values and start a
new series of readings. These display values can also be cleared without starting a new
cycle by pressing the
STOP
button successively until the MAIN MENU is displayed.
5.3 AUTO BLOCKAGE DETECTION
The Halimeter
PLUS is equipped with flow rate
detection to protect against unwanted blockages in
the inlet line. In the event of a sudden drop in
flowrate in ON or SAMPLE modes, the screen
shown to the right will be displayed. This indicates a
blockage of the inlet tube that must be addressed
before sampling can resume.
Should this message appear, check the tubing for any blockages or kinks that might restrict
flow. Clear this blockage then press the
ENTER
button to proceed.
