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 the Product Selection “Table 1 or Table 2”. The value should be within
±10%.
Also, measure the resistance between the white, black and shielding/ground wire. Both should read infinity.
Please refer to “5 Commissioning” for instructions on how to measure the resistance.
Important: measure the resistance four times during the installation process
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).

is free from defects in material, design and workmanship. The warranty is only valid if the warranty
certificate has been properly completed and mailed, and the installation is in accordance with the
