POWERTHEMETER

Pressthe buttontoturnonthemeter.Thebatterysymbolinformstheuserastothebattery

strength.Connectthebatterychargertorechargethebattery.Longpressthebuttonto

poweroff.TheLCDwillcountdown:3,2,1,thenOFFbeforeswitchingoff.

GERNERALUSE

AllLCDdisplaylineswillswitchONwhenpowerisappliedtothemeter.ThebottomTVOC

displaywillcountdownfrom10secondsorfrom90seconds(dependingonthe

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
