The only means of checking that the instrument’s detection function is working
properly is the

- At least once a year following the use and the type of sensor
- whenever the instrument has been exposed to overly high concentrations of
gas
- when an instrument has been stored for more than one month and without

- when fault appears
Within the calibration the menu "visible and audible" alarms are not triggered.
