Failure to perform an air calibration after reset- ting the analyzer to its factory settings may cause incorrect gas readings to be displayed. Battery Charging When the ‘BattLow’ message s dsplayed (refer to Secton 2.9), the ana- lyzer must be recharged usng the suppled battery charger. Important! The battery has a long shelf life, but it is recom- mended that the battery be recharged once a month if left unused. Batteries that have not been charged for several months should be given at least two charge/discharge cycles before using the analyzer. As wth all rechargeable batteres, there are gudelnes that should be observed: The battery should normally be charged at room temperature. Chargng at temperatures below 54°F (12°C) should be avoded snce ths may cause a false ndcaton of when the battery s charged, and could also damage the battery. Before beginning the charging process, first ensure that the analyzer is swtched OFF. Next, plug the suppled charger nto the approprate AC wall socket (an optonal 12 VDC vehcle charger s also avalable). Then plug the charger’s output connector nto the analyzer’s chargng socket (Fgure 1, Item H). -
