Electric Heat Tracing
content.thermon.comThe insulation resistance (IR) test establishes the electrical integrity of the trace heater. For the flexible trace heaters covered in this document, the IR test should be performed with a megger capable of delivering a voltage of at least 500 Vdc. It is strongly recommended that polymeric insulated trace heaters should be tested at 2500 Vdc. 1.

www.testequipmentdepot.comthe test site. What is a Low Resistance Measurement? A low resistance measurement is typically a measurement below 1.000 ohm. At this level it is important to use test equipment that will minimize errors introduced by the test lead resistance and/or contact resistance between the probe and the material being tested. Also, at this level, standing
