Theresistanceshouldbemeasuredfromtheinnercoreoftheyellow(120V)orred(240V)leadwireatoneendtotheinner
coreoftheblackleadwireattheotherend.Makesurethattheprobeoftheohmmeterdoesnottouchthetinnedsheath
wireateitherend.Donotholdthewiresontotheprobeswithyourngers.Evenyourbody’selectricalresistancecan
affectthereadingifyoutouchthemeterpoles.Adigitalmeteriseasiertouseandstronglyrecommended.Verifythatthe
batteriesoftheohmmeteraregood.Setyourohmmetertomeasureresistanceintherangeof0to200Ω.
Forcablesthathaveover200Ωresistance,itmaybenecessarytosettheohmmetertothenexthigherrangeof
measurementtogetanaccurateohmreading.
Three(3)ohmreadingsshouldbetakenforeachWarmlyYoursTempZone™FloorHeatingCableateachstageofthe

The ground wire may differ from the images above.
The ground wire may be represented as a additional wire with a stripe.
The testing procedure is still performed the same way.
