environment)tozero.Whencountdowniscompletethemeterisreadyforuse.

Innormalmode,thetopdisplayindicatestheHCHOconcentrationinPPMormg/m³.The

bottomdisplayindicatestheTVOCconcentrationinPPMormg/m³.

UsetheUNITbuttontoswitchunitsbetweenPPMandmg/m³.

Withthemeteron,ifthemeasuredHCHOconcentrationexceedsthehighorlowuser‐

programmableAlarmthresholds,theLEDdisplaywillflashredincolorandtheaudible

beeperwillsound(unlessithasbeendisabledwiththeSET/▼button).PressSET/▼to
