Performance Test Report
I. Overview
    1) Test Purpose
  Through the analysis of test results, evaluate the product performance; assess whether the tested product meets the technical requirements; provide reference data for product design and after-sales service, and provide a solid basis for factory shipment.
    2) Basic Information
Factory Serial No.: YLT260819-402 Product Model: DXHC10-200
Product Name: One-dimensional Coil Test Date: 2026-10-09
    3) Test Environment
The test environment is selected to be closer to the actual operating conditions of the user, including factors such as lead length and ambient temperature. The time is chosen during a period with smaller geomagnetic field fluctuations. Before testing, the required instruments are powered on in advance for warm-up, and the measurement environment is recorded as shown in Table 1.
