Calibration
Dräger recommends a device calibration every 12 months, because of
the sensor drift the uncertainty of measurement increases over
months. Instrument calibration and maintenance should only be
carried out by authorized persons, e.g. DrägerService.
The last 30 days before next service is needed, a day count down will
be shown as information in the display after switching on the device.
Please confirm this information with the button. It shall remind you that
the device needs to be serviced in the next days. After the service
date, the device starts to count up how many days it is over the
requested service. This information can be confirmed by pressing the
button as well.
