To avoid cross-talk or side-wall interference, engineers must maintain a clear radial distance of at least 76 mm (3.0 inches) from any adjacent metallic objects. Standard factory calibration is performed with AISI 4140 steel targets; using other target alloy profiles will result in scale-factor deviation.\n\u003c\/p\u003e\n\n\u003ch4 style=\"color: #2b6cb0; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003e\n  When routing the unarmored 9.0-meter integrated coaxial cable, ensure the minimum bend radius of 25.4 mm (1.0 inch) is strictly observed to prevent fracturing the inner conductor.
