Loop Installation

The loop(heat-resisting Teflon wire)is normally buried in a parallelogram form gap. After the test, seal the gap with liquid pitch. 1 to 2 circles of loops should be added as compensation when there are metal things under the ground. And the inductance should be kept at 150-300uH.The lead time must be twisted together closely, so as to prevent the disturbance caused by shock.
