The Bm829s "Dual Display" professional multimeter from Taiwanese company BRYMEN, one of the leading manufacturers of high-quality measuring instruments. The BM829s has an innovative AutoCheck function that allows automatic measurement of ACV, DCV and R without selecting a specific function. In doing so, voltages are measured with reduced impedance - which is of great importance when measuring electrical installations. The BM829s measures the true rms value (True RMS) of AC currents and voltages also with a DC component in the frequency band of 40Hz~20kHz for voltages and 40Hz~1kHz for currents. SPECIAL FEATURES AND FUNCTIONS: AutoCheck - automatic selection of LoZ DCV, LoZ ACV, ? through input signal analysis and the instrument's internal algorithm that provides impedance-reduced measurements (BM 829s) CREST - registration with automatic change of ranges of MAX, MIN, MAX-MIN (Vp-p) values of pulses of not less than 1ms duration REC - 50ms registration with automatic change of ranges of MAX, MIN, MAX-MIN and AVG (average) values from measurements BEEP-JACK - acoustic and visual alarm for bad connection of measurement wires EF-Detection - non-contact detection of the presence of AC voltage using an antenna located at the top of the case.
