Fluke 353 AC/DC True RMS Clamp Meter
With extremely large size jaws with capacity of 58mm (2.3″) the Fluke 353 AC/DC True RMS Clamp Meter can be used to accurately test medium, large and even multiple conductors at the same time.
Once attached to a conductor this clamp meter can be used to measure current levels across three ranges of 40A, 400A and 2000A (1400 AC rms) for both AC and DC modes. This tester also contains a crest factor mode which is available at either 50 or 60Hz.
Test readings are shown automatically on the LCD screen on the front of the 353 and it is also possible to generate MAX, MIN and AVG functions as well based upon this testing data. The screen is even backlit, making seeing the tester easy in darkened or poor lighting conditions.
It is also possible to hold a test reading on screen using a data hold function and the 353 also includes a low-pass filter which smooths out noisy loads and ensures reading stability.
An upgraded version of the Fluke 353 (the Fluke 355) contains the ability to carry out additional measurements such as voltage and resistance.
