The contact resistance of conductive polymer bumps, 50 [[micro]meter] high on gold, has been measured repeatedly in the 15 to 25
milliohm range.
Two DC resistance meters accurately measure resistance in the
milliohm range.
The units include a digital port with external triggering and remote-inhibit functionality, a built in 5 1/2-digit voltmeter, a
milliohm meter supporting four-wire measurements, memory for storing 50 parameters, and fan-speed control to minimize audio noise.
A high-volume manufacturer of batteries for a cell phone company originally used a test system designed with Agilent Technologies' instruments including the 3499A Switch/Control Mainframe, the 34401A DMM, 6652A and 6624A DC Power Supplies, a 6060B Electronic Load, and a 4338B
Milliohm Meter.
