BM 878 professional multimeter (RISO, VFD ACV&Hz, 5kHz True RMS(ACV), mA-AC/DC, Temp, TrueRMS) SUPER MULTIMETER + INSULATION RESISTANCE TEST + CONTINUITY TEST Insulation resistance measurement up to 25G (test voltages 50~1000V), continuity test with current >200mA. BM 877 additionally determines PI and DAR indicators and has a comparator. The instrument is equipped with special test leads for insulation resistance and continuity measurements (so-called remote measurements are also possible). The innovative "Smooth" function allows smoothing of unstable measurement readings. BM 878 is an advanced multifunctional industrial multimeter with a high degree of measurement safety and overload protection. SPECIAL FUNCTIONS AND FEATURES: RISO - insulation resistance measurement with test voltages of 50V-100V-250V-500V-1000V. High max resistance ranges from 55MΩ (50V) to 25GΩ (1000V). VFD ACV & Hz - simultaneous voltage and frequency measurement suitable for measuring - outputs of Variable Frequency Drives (VFDs) Loock-Test mode - for making continuous measurements with 2 measurement probes. 200mA TEST Continuity test of equipotential and protective conductors with current >200mA BEEP-Jack - acoustic and LCD signaling of incorrect connection of measuring wires in relation to the selected measuring function REC MAX/MIN/AVG Recording of maximum, minimum and average values.
