SAFETY WARNING!
CO is life threatening even at low concentrations.
Ensure you understand the risks before investigating
This monitor measures combustion gases that may be toxic in relatively low
concentrations.
This monitor must only be used by trained and competent persons
after due consideration of all the potential hazards.
Portable gas monitor users should conduct
“
bump
”
test before relying on the
monitor to verify atmospheres are free from hazards.
A
“
bump
”
test is a way to check a monitor works within acceptable limits by
briefly exposing it to known gas mixtures formulated to change output of all
sensors present.
NOTE: This is different from calibration where the monitor is exposed to
known gas mixtures but allowed to settle to a steady figure with readings
adjusted to the gas concentration of the test gas.
A bump test can be conducted using a disposable canister of CO
sometimes used to check domestic CO alarms.
