Fluke 1625/1623 GEO Earth Ground Testers

소개

Fluke 1623, 1625 모델은 4가지 형태의 접지측정이 가능한 뛰어난 접지테스터입니다. 특히 “Stakeless testing”이라고 불리는 오직 클램프를 이용한 접지측정 방법으로 접지봉을 박거나 접지선을 제거하지 않고도 접지저항을 측정할 수 있습니다.

특징

• 2개의 접지봉을 이용한 3극, 4극 접지측정
• 접지봉과 클램프를 이용한 Selective testing
• 클램프 2개를 이용한 Stakeless testing

측정방법

• 2개의 접지봉을 이용한 3극, 4극 접지측정
• 접지봉과 클램프를 이용한 Selective testing
• 클램프 2개를 이용한 Stakeless testing

Fluke-1625만의 특징

• Automatic Frequency Control(AFC) – 주파수간섭을 최소화
• R* measurement – 55Hz에서의 접지 임피던스를 측정
• 한계값 조정 – 테스트 결과값을 빠르게 확인
