1.3 Remember to measure resistance
The resistance should be measured between the two conductors, white and black. Compare this resistance
reading to the resistance specified in table below. The value should be within -10% to +10%. If you get
a different reading, contact to the distributor. Also, measure the resistance between the white, black and
shielding/ground wire. Both should read infinity. If you get a different reading, contact to the distributor.
Please refer to “5 Commissioning” for instructions on how to measure the resistance.
i Important: measure the resistance four times during the installation: Remember to always
measure, verify and record the actual resistance throughout the installation process (out of the box, after
installation, after thin set cement or self-leveler application and after installation of floor tiles)
