Fluke 376 True-rms AC/DC Clamp Meter with iFlex™

- By Fluke India

Overview

• Fluke 376 Clamp Meter is 1000A AC/DC Clamp meter

• It offers improved performance perfect for a wide range of current measurement situations.

• With True-RMS measurements, the Fluke 376 can read up to 1000 A and 1000 V in both AC and DC systems.

Application

• Current measurement in high power, high current switchboards up to 2500AC or 1000A DC

• High capacity Ac/DC motors and other industrial loads

• True-RMA measurements on non-linear signals like thyristors, semi-conductors, UPS, rectifiers etc.

• Measure current around bus bars and other high size cable using iFlex Flexible CT where conventional Clamp cannot measure.

• Inrush current measurement on loads i.e motors or lighting circuits

Features & Benefits

• As per IEC 61010 part 2, CAT IV 600 V, CAT III 1000 V

• iFlex flexible current probe expands the measurement range to 2500 A ac

• True-RMA ac voltage and current for accurate measurements on non-linear signals

• Min, max, average and inrush recording to capture variations automatically

Features & Benefits

• Integrated low pass filter and state of the art signal processing allows for use in noisy electrical environments while providing stable readings

• Proprietary inrush measurement technology to filter out noise and capture motor starting current exactly as the circuit protection sees it

• Ergonomic design fits in your hand and can be used while wearing protective equipment

Features & Benefits

• Large, easy to read backlight display automatically sets the correct measurement range so you do not need to change the switch positions while taking a measurement

• Three-year warranty

• Soft carrying case

True-RMS“RMS” stands for root-mean-square. It comes from a mathematical formula that calculates the “effective” value (or heating value) of any ac wave shape. Electrical power system components such as fuses, bus bars, conductors, and thermal elements of circuit breakers are rated in rms current because their main limitation has to do with heat dissipation. If we want to check an electrical circuit for overloading, we need to measure the rms current and compare the measured value to the rated value for the component in question.

If a current clamp is labeled and specified to respond to the true-rms value of current, it means that the clamp’s internal circuit calculates the heating value according to the rms formula. This method will give the correct heating value regardless of the current wave shape.

Certain current clamps, which don’t have true-rms circuitry, use a short cut method to find the rms value. These meters are specified to be “average responding/rms indicating.” These meters capture the rectified average of an ac waveform and scale the number by 1.1 to calculate the rms value. In other words, the value they display is not a true value, but rather is a calculated value based on an assumption about the wave shape. The average responding method works for pure sine waves but can lead to large reading errors up to 40 percent, when a waveform is distorted by nonlinear loads such as adjustable speed drives or computers.

Make sure your customers are buying True-RMS clamps for their trouble-shooting needs!
