BENNING MM 10-1 - TRUE RMS Digital Multimeter with Bluetooth and AppNon-linear loads, such as those generated by variable speed motor drives, frequency converters or power supplies for office equipment and LED lights, generate reactive power in the mains. As a result, multimeters and current clamps with the root-mean-square (RMS) measuring method display the measured values less accurately. In many cases, and especially in industrial environments, the use of modern true RMS measuring instruments is necessary. The TRUE RMS measurement method correctly displays the true, effective value of an AC current - regardless of whether the waveform of the current is sinusoidal or distorted.Features: -Ideal for the heating and plumbing professional -Voltage up to 1000 V AC TRUE RMS / DC -Current 0.1 µA - 400 mA DCAC -LPF low pass filter to suppress high frequency noise -Measurement of temperature, resistance, frequency, capacitance -Continuity and diode testing -LCD display with backlight -Voltage sensor / cable break detector -Measurement memory: HOLD, MAX / MIN, REL, SAVE -Rubber protection frame with integrated magnet -Measurement category: CAT IV 600 V, CAT III 1000 V -Incl.
