Important note:
Before repeating a measurement the unit must be turned off,
and the mouthpiece and adapter removed for at least 1
minute. This is to allow re-equilibration with ambient air and
to dry the surface of the sensor. Visually inspect that all
moisture has evaporated from the surface of the sensor
before reuse.
If the unit is switched on again too quickly after use there
may be a response to residual expired carbon monoxide from
the previous test.
In this case the display will show:
Gas
If this is displayed then turn the unit off, remove the mouthpiece
adapter, and expose to ambient air for 2 minutes before repeating
the test.
Note:
If this warning appears again after following the above
procedure then turn off and leave the sensor exposed to ambient air
for a further 3 minutes. If the same message appears again then
this indicates possible contamination of the sensor with a solvent.
In this case remove all sources of solvent from the vicinity of the
sensor and expose to ambient air for 24 hours before switching on
again.
