The VOLTCRAFT handheld multimeter VC 191 is your multimeter with absolute top equipment in the compact VC 100 series. Impedance switchingThe LoZ function makes it possible to measure alternating voltages with low impedance. The lower internal resistance of the measuring device reduces the measurement deviations due to stray and ghost voltages. Switchable low pass filter (LPF)In digitally controlled motors, unwanted modulated control signals are ignored for the measurement. Delta measurementFor measuring deviations of a specified value. This allows you to focus on the positive and negative changes and does not have to reckon with all the time.Sample ratioMeasurement rate or duty cycle refers to phase angle control, switched-mode power supplies and other digital switched devices to determine the percentage value between ON (pulse) and OFF.Min MaxThe highest and lowest values of a series of measurements are saved and displayed.Start-up tipsVery short signal events, which last just one mil
