Testing

At each stage of the installation it is recommended that the heating mat is tested

for the following:

Continuity- This checks that the heating cable (blue and black wires) are intact

and have the correct resistance. The resistance is checked with a multimeter

and the reading should match the resistance rating on the label on the cold tail of

the Devimat

™

with a tolerance of -5 to +10%. Ensure your multimeter is capable

of reading values between 28-550 ohms.

Insulation- This checks that the earth screen around the heating cable has not

been damaged and shorted to the heating cables. The test can be made with a

multimeter and can be done by testing the path between the blue cable and the

earth screen and the black cable and the earth screen, both should read inﬁ nity.
