Electric heating cable in the factory, the manufacturer will carry out strict testing to ensure the quality of electric , but in the heating cable transportation and installation process, due to negligence or non-standardized installation will appear to damage the electric heating cable, resulting in electric accompanied by heating system operation is not normal, so in the receipt of the product and installation is completed need to be electric heating cable for testing, before the user consults us multimeter can be detected, of course, then how to detect it, below is a brief introduction. Of course you can, then how to detect it, the following brief introduction, I hope to help you.

                         Multimeter test electric heating cable mainly test the resistance of tropical, can detect the electric heating cable is damaged, and in the wiring, terminal line, electric heating cable and electric heating cable wiring there may be a short circuit, leakage and other problems, electric heating cable with the use of multimeter test is divided into the following steps:
　　              1. Preliminary detection: as mentioned before, in the electric heating cable installation before;
　　              2. Acceptance test: in the electric heating cable, accessories installed, insulation installation before;
　　              3. Before the power test: this test in the insulation is completed, before the system is energized.
　　              In the actual measurement, to use the low voltage DC500 V, high voltage DC1000V for testing, no matter how long the system is, insulation resistance at least 10Mohm for each electric accompanying heat circuit.

                    1. Electric heat tracing cable tape with protective braid and jacket: Measure between each electric heat tracing tape cable conductor and protective braid, and also measure between protective braid and grounding pipe.
　　            2. Electric heat tracing tape without braided jacket: Measure between each power conductor of electric heat tracing tape and grounding pipe or thermally insulated grounding steel sleeve.
　　            Notes:
　　           1. Measure the insulation resistance from right to left reading, the right side is 0, the left side is ∞.
　　           2. Insulation resistance value more to the left (∞) insulation is stronger, the more to the right (0) insulation is worse. (Insulation resistance measurement value more get higher) unit for MΩ.
　　           3. The electric accompanies the tropical should not have the outer skin damage state sealing end, cut off the water is strictly prohibited.
　　          The above is a brief introduction to the electric accompanied by the tropical detection, if you still have what do not understand in the use or detection process, you can consult us at any time, do not solve the problem by yourself, so as not to cause failure, can not be used.
