Product Introduction
It can perform automated laboratory level verification of protection level (P level) and metrology level CT/PT in the on-site environment, with single machine operation (zero external attachments), automatic inflection point detection, 5%/10% error curve generation, and reporting functions in accordance with GB 20840.3-2013/IEC standards. Its portable design with a weight of ≤ 22kg integrates a thermal printer for real-time on-site reporting, 3000+battery supported test records, and one click USB Word report generation, reducing debugging time by 70% while ensuring practical accuracy.
