Elma BM789 multimeter TRMS in slim design

Elma BM789 is a slim multimeter with a high bandwidth of 100kHz and true RMS measurements. Auto Check is an intelligent function that automatically detects and selects AC voltage, DC voltage and throughput test / resistance. All you have to do is turn on the instrument and measure. Low Z is voltage measurement with low impedance, ie the measuring point is loaded and thus it is ensured that the real voltage is measured and the ghost voltage is discharged. In addition, the Elma BM789 has advanced VFD (Variable Frequency Drive) function, which means that it can measure accurate voltage according to e.g. frequency converters and other power electronics, where standard multimeters must give lost.
