Operation

Poweringthemeter

Ifthemeterissuppliedwithoutbatteriesinstalled,installthesuppliedbatteriesintherear

batterycompartmenttopowerthemeter.Pleaseobserveproperpolarity.

Ifthemeterissuppliedwiththebatteriesinstalled,andaprotectivebatterystripisinstalledin

thebatterycompartment,removetheprotectivestriptopowerthemeter.

Alternatively,pluganACadaptorintothejackonthesideofthemeterandthenintoanAC

powersourcetopowerthemeter.

NormalOperatingMode

WhenswitchedON,theLCDdisplays‘0000’foraperiodoftime,dependingonthetimethatthe

meterhasbeeninactive.Themeterwillthenproceedtothenormalmodeofoperationwhere

theLCDdisplaysthecurrentHCHOlevelinppm,theTemperature(°C/°F),andRH%(relative

humidity)alternatelyat6secondintervals.

Multi‐ColorStatusIndicatorLED

TheFrontpanelstatusLEDusesacolor‐codingsystemtoinformtheuserastothemeasured

HCHOconcentration.GreenforGood;YellowforHazard;RedforDanger.IftheLEDfailsto

illuminatepleasereturntheunitforservice.

Alarmindication

WhentheFormaldehydelimitof0.08ppmisexceededthemeteraudiblybeepsandflashesan

alarmiconontheLCD.RefertotheCONTROLBUTTONsectiontolearnhowtosilencethe

beeper.

ControlButton

TheControlbuttonlocatedontheleftsideofthemeterisusedtocontrolandprogramavariety

ofmeterfunctions.PressandholdtheControlbuttontoenterthefunctionmode.Repeated

pressesofthecontrolbuttoncyclethroughtheavailableparameters.Theseparameters,in

order,are:

ZEROCalibration

TemperatureUnitselection(°C/°F)

Temperaturecompensation(usedinconjunctionwithsidepotentiometeradjust)

Humiditycompensation(usedinconjunctionwithsidepotentiometeradjust)

Unitofmeasurechange(ppmormg/m3)

AlarmBeeperON/OFF

FactoryDefaultsettingreset

Escape/Return(abortoperationandreturntonormaloperation)

Note:Aremovablecoverprotectstheoffsetadjustmentandpreventsunintentional

adjustment.Removetheprotectivecovertoperformanoffsetadjustment.
