Calibration Certificate of DX-350 3D Gauss Meter
Manufacturer: Vivo Mobile Communication Co., Ltd.
Calibration Date: June 12, 2023
Model/Type: DX-350
Serial No.: 202305007
Client: Xiamen Yingdexing Magnetic Electric Technology Co., Ltd.
Laboratory Address: No.163, Pingyun Rd, West of HuangPu Ave, Guangzhou, Guangdong, China
The calibration was conducted in accordance with ISO/IEC 17025:2017 standards, ensuring traceability to the International System of Units (SI). The calibration results are valid only for the sample tested and should not be reproduced without written approval from the laboratory.
The calibration involved the verification of magnetic induction across three axes (X, Y, Z) with various reference values. The results showed minor indication errors, all within acceptable limits, resulting in a "Pass" status for all measurements.
Calibration was performed at the Guangzhou Metrology Electromagnetic Room under controlled temperature and humidity conditions.
The suggested calibration interval is one year, but it can be adjusted based on actual usage conditions.
The calibration adhered to the JJF 1832-2020 standard for magnetometer calibration and JJF 1059.1-2012 for the evaluation and expression of measurement uncertainty.
