● 1MA의 누설 전류를 측정할 수 있다는 것은, 저-전압 회로들과 전기적인 부품들의 절연상태를 점검하는데 유용하다는 말과 같습니다.
● 60A 이상 넓은 폭의 레인지를 측정할 수 있습니다.(0.001MA의 분석력)
● 외부 자기장 0.0005%로 부터 전형적인 영향(근접 케이블의 전류 값)
● CLAMP의 내구성 : 50,000회 이상 개/폐 하여도 이상이 없습니다.
● 요꼬가와社 초기 CLAMP 모델이기 때문에 2배의 강력한 내구력
● CLAMP 누름쇠는 지름 40MM 두께의 케이블을 위해 CLAMP의 부드러운 개/폐의 정도를 30% 강화 시켰습니다.
● 안전 규격 EN61010-1(CATⅢ300V, POLLUTION DEGREE2) |

| Note |
- Can measure leakage currents of 1 mA, which is useful for checking the insulation of low-voltage circuits and electrical components.
- Can measure a broad range of currents from leakage currents (at a resolution of 0.001 mA) to load currents up to 60 A.
- Typical influence (on the current value of an adjacent cable) from an external magnetic field is 0.0005%.
- Durability of clamp: More than 50,000 opening/closing events
- Twice the tensional strength of Yokogawa M&C''s earlier model clamps
- The clamp lever is lengthened by 30%, enabling smooth opening/closing of the clamp even for thick cables of 40mm in diameter.
- Approved for conformity to safety standards EN 61010-1 and EN 61010-2-032 (CAT III 300V, pollution degree2)
