SafetyInstructions
Personneloperatingandmaintainingthedevicemustbefamiliarwithallaspectsofits
operationandbeproficientinmaintenance.
SuchPersonnelshouldreviewthefollowingprecautionstopromotesafetyawareness.
General
•Alwaysrefertothemanualbeforeoperatingormaintainingtheequipment.

•Donotopenthedevice.IncaseoftechnicalproblemspleasecontactTendringPacific.
•Donotcoverthemachinewithaclothorpieceofplastictoprotectitfromdust,asthis
preventsfreeaircirculationaroundthemachineandmightleadtooverheatinganderrors
inthesensorread‐out.
•Donotexposetheequipmenttoheavymoistureorheatandkeepitawayfromdirect
sunlight.
•Nevershortcircuitorremovesafetydevices.

Installation
•Toensurethebestinstallationwiththeleasttechnicalproblems,pleaseinstall
equipmentasdescribedinthemanual.
•Neverinstalltheequipmentinexplosiveenvironments.
•Alwaysusecorrectfittingswhenconnectinggasfromthegasbottle.
•Provideadequatespacearoundtheequipmentforproperventilation.
•TheunitsareClass1appliancesandmustbeconnectedtoanearthedmains connection.
•Itistheresponsibilityoftheownerandoperator(s)oftheequipment,thatthe
installationismadeinaccordancewithlocalrulesandregulations.

NOTE!Apartfromthebelowdescribed“Offset(20.9%O2) 
calibration”allcalibrationproceduresmustbecarriedoutby
DansensortrainedServiceTechniciansonly,ascalibrationrequires

Itisrecommendedtoperformanoffset(20.9%)oftheO₂sensorevery
daybeforestartingmeasurements.Thisistocompensateforsensorwear.

Revision1
Note!Asaminimum,aweeklyoffsetcalibrationisrequiredtoretain
the12monthscalibrationintervals!

Alsowhenmovingthedevicefromcoldtowarmtemperaturesorviceversa,you
shouldallowthedevicetostabilizeforapprox.10‐15minutes,thenperform
offset(20.9%)calibrationoftheO₂sensorrightbeforeeachmeasurementseries
untilthedevicehasstabilized.Thiswillbringthecalibrationbackinlinewiththe
currentresponse.

Tomakeoffset(20.9%)calibrationdothefollowing:‐

1.Placetheneedleonthetablenexttothedevicetomakesurethatitmeasures
