2.3 Resistance Test
Measure the resistance of the EFMA heating cable at each step using a multi-
meter (Fig. 2.3) and record readings on the measures’table.
IMPORTANT!
For the warranty to be valid, ll out the measures’ table and ensure that the
10 readings have been correctly noted.
A qualied 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 o (see Table 2.1) at any step, stop work and contact REZNOR’s
technical specialists at 1800695-1901.
