Setting Reference Values
Setting a Reference PEF or FEV1 for color-zone display:
1.
Press the Operate button quickly 4 times during 2 seconds. The
PEF or FEV1 indication starts blinking. The display will show
the stored reference value, (000 for first time setting).
2.
Release the button, then each press will advance the display by
10 LPM for PEF, or 0.10 Liter for FEV1.
3.
Hold the button for more than 5 seconds to save the desired
reference value. The PEF or FEV1 indicator will stop blinking
and a beep will sound.
4.
The display will show briefly the new reference value and return
to show the last test results.
Notes:
•
During the reference setting process, if the button is not pressed
within 5 seconds, the unit will exit the Setting Mode without
modifying the old reference. The display will return to the last test
results.
•
The color-zone and relative warning indicator in the memory
review mode will reflect the new reference value.
•
The entire memory bank can be erased by setting the PEF
reference to 10, or the FEV1 reference to 0.10.
•
The optional accessory software can be used to toggle between
displaying the color-zone relative to the PEF or FEV1 reference.
•
The optional accessory software can be used to modify each
color-zone limits, in 10% increments.
