2.3 Resistance Test
Measure the resistance of the Therma Cable heating cable at each step
using a multimeter (fig. 2.3) and record readings on the measures’ table.
For the warranty to be valid, fill out the measures’ table and ensure that the
10 readings have been correctly noted.
A qualified electrician must measure the system’s resistance as follows:
- Use a calibrated multimeter only;
- Measure resistance at the free end of the cold lead, between the two phase
conductors;
- Write the reading in the measures’ table;
- Verify the heating cable integrity by comparing your reading to the value on
the cold lead label;
- If your reading is off or very different than the nominal resistance (see Table 2.1)
at any step, stop work and contact Ouellet Canada Inc.'s technical
specialists at 1 800 463-7043.
