True-rms 2000 A Clamp Meters High current and a large jaw, make these clamps well suited for industrial and utility applications Confidently take reliable readings with the true-rms, Fluke 355/353 Clamp Meters; the tools of choice for high-current measurements up to 2000 A. The extra-wide jaw easily clamps around large conductors typically found in high- current applications. The rugged design and CAT IV 600 V, CAT III

1000 V ratings, add an extra ele-

ment of protection when taking high-powered measurements. Accurate peak measurements can be taken using the in-rush current mode, ideal for motors and inductive loads. The 355 also measures voltage and resistance, making this the most versatile tool for utilities, electrical contractors, and industrial service technicians.

  • Reliably handle a wide range of high-current applications with 2000 A ac + dc true-rms,

1400 A ac, and 2000 A dc

  • The large 58 mm (2.3 in) jaw capacity is suitable for large, or multiple conductors
  • CAT IV 600 V, CAT III 1000 V rating for added user protection
  • In-rush current measurement captures ‘power-on’ surge current with accuracy and repeatability
  • High voltage measurement of 1000 V ac + dc true-rms, 600 V ac, and 1000 V dc allows users to perform multiple tests with only one tool (355 only)
  • Resistance to 400 kW coupled with a continuity beeper, provide the convenience of a multimeter (355 only)
  • Accurately measure frequency up to 1 kHz for optimum troubleshooting
  • Quickly analyze readings using the MIN, MAX, and AVG functions
  • A large backlit display allows for easy visibility in low-lit areas
  • Use the display hold feature to capture readings even when the display cannot be viewed
  • Use the low-pass filter to smooth out noisy loads and stabilize readings N10140
