Resistance MeasurementsThe HP 34401A offers two methods for measuring resistance: 2-wireand 4-wire ohms. For both methods, the test current flows fro

True RMS AC Measurements True RMS responding multimeters, like the HP 34401A, measure the“heating” potential of an applied voltage. Unlike an “average

An ac-coupled true RMS measurement is desirable in situations whereyou are measuring small ac signals in the presence of large dc offsets.For example,

To Select a Range You can let the multimeter automatically select the range usingautoranging or you can select a fixed range using manual ranging. •

To Set the Resolution You can set the display resolution to 41⁄2, 51⁄2, or 61⁄2 digits either tooptimize measurement speed or noise rejection. In th
