  • Reliably handle a wide range of high-current applications with 2000 AC/DC True-rms, 1400 A ac, and 2000 A dc
  • The large 2.3" (58 mm) 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 user to perform multiple tests with only one tool
  • Resistance to 400 k Ohms and a continuity beeper provide the convenience of a multimeter.
  • 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

Confidently take reliable readings with the Fluke 355 AC/DC True-rms Clamp Meter - the tool of choice for high-current clamp-on amp meter measurements up to 2000 A. The extra-wide jaw easily clamps around large conductors, typically found in high-current applications and the extra rugged design has an extra element of user protection when taking high-powered measurements.

Industrial plants and large facilities often have equipment and installations that draw greater than 1000 A. As with other current measurements, it is not practical to disconnect the equipment to make a series of current measurements. The ability to check that an expensive system has been installed correctly, troubleshoot large loads, and make accurate measurements on UPS and Variable Frequency drives with noisy loads is also essential. In industrial settings, compliance with NFPA 70E safety standards, while making measurements, is critical. Fluke has addressed this by designing this product to meet CAT IV 600 V and CAT III 1000 V ratings.

Accurate peak measurements can be taken using the in-rush current mode, ideal for motors and inductive loads. Additionally, the Fluke 355 measures voltage to 1000 V DC and 600 V AC (True-rms) and resistance to 400 k ohms with a continuity beeper, allowing utility technicians, electrical contractors and industrial service technicians to perform multiple tests with only one tool.
