The Keysight U1241C is a handheld True RMS digital multimeter delivering 4-digit resolution and 10,000-count display capability for field and benchtop measurement tasks. It combines DC/AC voltage and current measurement with resistance, capacitance, and frequency analysis in a single portable instrument. The True RMS engine ensures accurate readings of non-sinusoidal waveforms across voltage ranges from 600.0 mV to 600.0 V and current ranges from 600.0 µA to 10.00 A.
