The battery-powered true RMS multimeter BE52 with integrated torch was specifically designed for safe usage in rough environments. With ten different functions for the most frequently required measured variables, the particularly durable ammeter covers a variety of possible applications in the DIY, handicraft, hobby and motor vehicle sectors. Whether you wish to carry out measurements in the field of housing and building technology, in the professional domain with electricity, occasional repairs of household appliances and electronic equipment or for problems in the vehicle electronics – the BE52 impresses with its excellent variety of functions and features even under the most adverse outdoor conditions. Wherever electricity flows, the multifunction measuring meter renders invaluable services for installation and troubleshooting.

Perfectly equipped for almost any power, voltage, capacitance and continuity measurements

With the BE52, DC and AC voltage measurements, direct current and alternating current measurements, capacitance measurements, frequency/duty cycle measurements resistance measurements, diode tests as well as acoustic continuity tests can be carried out.

Particularly durable and powerful true RMS multimeter

The measured values are shown in a clearly legible fashion on the large LC display with optional background illumination. Thanks to the practical hold function, the measured values remain readable even after you have completed the measurement process. When you carry out a continuity test, an acoustic signal indicates a short circuit or a closed circuit and therefore speeds up your work progress, since you do not have to keep your eyes on the display during the measurement. A fold-out foot that is integrated on the rear of the device allows you to keep both hands free for performing your measurement tasks. In this way, the measuring device can be put down onto an even surface in a position that makes it easy for you to read off the measurement results. The automatic switch-off mechanism of the device (auto power off) which responds after the device has been inactive for 15 minutes preserves the battery and is a practical feature.

Evaluation and documentation including MultiMeasure Mobile app

As a true RMS digital multimeter of the latest generation, the BE52 is 100 per cent "MultiMeasure Mobile ready" and thus prepared for all requirements of professional measurement data evaluation and documentation. Via the integrated Bluetooth^® interface, the recorded measurement data is easily and conveniently transferred to a smartphone or tablet, where it can be professionally evaluated or recorded with the free MultiMeasure Mobile app.

The advantageous combination of the BE52 and professional MultiMeasure Mobile evaluation software allows you to make quick and reliable statements about electricity measurements at all times – including a wide range of analysis options such as the logging function for long-term measurements, graphic evaluations, the report function and data synchronisation with our professional cloud-based software MultiMeasure.

In the measurement process, a digital measuring device without true RMS function assumes that the AC signal is sinusoidal and therefore converts the raw signal measured to be displayed on the basis of this assumption. However, in fact, the electrical current flow is never purely sinusoidal. Consumers like switch-mode power supplies, speed or power controllers, etc. cause faults which in turn produce distorted current profiles. Since these profiles are no longer purely sinusoidal, they cannot be measured correctly without true RMS functionality.

True RMS measuring devices can also measure non-sinusoidal signal characteristics correctly and therefore are able to directly determine the true r.m.s. value of any alternating quantity. In this respect, the true root mean square stands for the correct determination and output of the true r.m.s. value.
