Equipped with an innovative display that flips down for easy visibility, the 329150 and 3293-50 are designed for efficient measurement of indoor wiring in a variety of environments, from factories, buildings, and offices to residences. ■ Easy to see, even on high or low locations ■ Easy measurement of wires on ceilings New Design Slim Sensor ? ● The ability to clamp even in crowded wiring locations ? Have you ever wanted... ● To have thinner clamp sensors ? K! Model 3291-50 can clamp on LOO wires spaced only 12.5 mm apart. Thin sensors let you clamp easily, even around closely spaced wires. 3291-50 3293-50 11mm 8mm Up to 30 mm in diameter Sometimes it’s easier to clamp the target wire at an angle. Up to 24 mm in diameter 3 Extensive current measurement functions 1 “True RMS” lets you measure even distorted currents accurately With “True RMS” measurement, the 3291-50 and 3293-50 accurately measure even distorted load and leakage currents. Two ways to convert alternating current to RMS are “true RMS response” and “average rectified RMS response” (averaging). Both display the same value for a sine wave, but can display very different values for distorted waveforms. Averaging True RMS response (the 3291-50 and 3293-50 work this way) High-frequency waveform components are included in the calculated RMS display value. When measuring current waveforms distorted by inverters… The measured waveform is treated as a single-frequency (undistorted) sine wave, and the calculated average of the ac signal is converted to an RMS display value. Measurement error increases with waveform distortion. As inverters and switching power supplies proliferate, the need for the capability to measure distorted current waveforms grows. A true RMS clamp-on current meter is the proper tool for accurate measurements. 2 Measure leak and load current with the 3293-50 The 3293-50 provides 6 ranges, from 30 mA to 1000 A. The 3291-50 provides 3 ranges, from 60 A to 1000 A. Range 30.00mA 300.0mA 3291-50 6.000A 60.00A Provides a high-frequency noise filter. When activated, the filter rejects frequencies above 180 Hz, approximating the filter characteristic of an earth leakage circuit breaker (ELCB) for measurements. Cuts high-harmonic components to measure the fundamental waveform (The filter in the 3293-50 is enabled by default.)
