Page01

ST6Seriesinstrumentsareintendedformeasurementoflowdifferentialairpressureinandaround
commercialandindustrialairhandlingsystemsandforusewithaPitotStaticTube,dpmAneTMhead,
dpmHoodanddpmShortHood.

Theinstrumentsarenotsuitableforliquidpressuremeasurementandmustnotbeusedwith
corrosive,toxicorotherwisehazardousgases.

Theinstrumentsarenotclassifiedas“Flameproof”or“IntrinsicallySafe”andconsequentlymustnot
beusedwhereanexplosionhazardmayexist.TheyarealsonotauthorisedforLifeSupport
applications.

Duringnormaloperationsmallquantitiesofair(typicallylessthan0.1ml/min)maypassintooroutof
thesystemundertestanditistheresponsibilityoftheusertoconsidertheconsequencesofsuch
leakagebeforedeterminingthesuitabilityoftheinstrumentforanyparticularpurpose.

Theinstrumentmustbeturnedoffbeforeitisstoredortransportedand,ifitistobestoredforalong
periodoftimeoristobetransportedbyair,thebatteriesmustberemoved.

Thereisa12‐monthguaranteeonallmanufacturedparts.
Thisguaranteedoesnotcoveranyconsumables,and/orwearandtearduringnormalorabnormaluse.

Theguaranteebecomesnullandvoidiftheinstrumentspartshavebeentamperedwith,misused,
abusedorusedoutsidetheparameterssetoutinthismanual.

Themanufacturerwilldetermineiftheinstrumentisrepairableorrequiresreplacement;chargesmay
