2.3 Resistance Test

Measure the resistance of the Thermat 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 very different from the nominal resistance at any step, stop

work and contact Ouellet Canada Inc.’s technical specialists at 1 800 463-7043.
