The only means of checking that the instrument’s detection function is working
properly is the calibration performed with the help of a standard gas.
Calibration must be done :
- 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
use
- when changing of sensors
- when fault appears
Within the calibration the menu "visible and audible" alarms are not triggered.
