3 MAINTENANCE
3.1 Maintenance involves preventive services, battery replacement and regular
performance check (according to 2.4.3 - 2.4.5).
3.2 Preventive services include external examination, dusting and decontamination
in the event of radioactive contamination.
For decontamination wipe the case of the dosimeter using a cloth wetted with
ethanol.
3.3 Battery replacement:
- unscrew and remove the cover of the battery compartment;
- remove the old battery;
- insert the new battery observing the polarity (the “+” sign of the battery should
be inwardly directed);
- fix the cover of the battery compartment in its place.
After the battery is replaced, the LCD will display all segments, and then the
dosimeter should enter the measurement mode. All the previous measurements and
parameters necessary for proper operation of the dosimeter are stored in its non-volatile
memory.
NOTE – Insert a new battery before sending a dosimeter for calibration.
