4. AREACHECK P2 requires a reference value representing clean air This reference value is taken and stored whenever the instrument is powered up or reset You should therefore make sure that power up takes place under clean air conditions A fresh reference value is also taken after manual reset via the key switch Therefore after each manual reset the instrument will temporarily only respond to SF6 concentrations exceeding the level that was present at the time of manual reset This will avoid the next measuring cycle to trigger an undesired new alarm The reference value will auto adapt to falling SF6 concentrations so after once meeting a clean air condition 5F6 AREACHECK P2 will automatically return to full sensitivity Since a reset is also performed when the instrument is taken into setup mode via the host computer interface the above also applies in this case After Power up or reset the first measuring cycle starts immediately beginning with the fan run time Measuring Interval Since SF6 AREACHECK P2 is designed to determine slowly changing concentrations it samples the air at a fixed time interval rather than measuring continuously This feature minimizes the amount of air per time that passes the instrument s intake system thus extending its service life Via the measuring time interval it is possible to perfectly adapt the instrument to the actual application For monitoring generally unattended spaces a long time interval sho
