Operation
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

BATTERYCHARGEandREPLACEMENT
1. Whenthebatteryrequirescharging,plugthesuppliedbatterychargerintothemeter(left
side,underflap)andtoasourceofACpower.Afullchargerequires2hours.
2. Toreplacethebattery,opentherearbatterycompartmentandreplacethePolymer
lithium‐ionbattery(7.4V1300mAh).Re‐assemblethemeterbeforeuse(part#VPC‐BATT)
BatterySafetyNotes:Pleasedisposeofbatteriesresponsibly;neverdisposeofbatteriesinafire,
batteriesmayexplodeorleak.Ifthemeterisnottobeusedfor60daysormore,removethe
batteryandstoreseparately.
