The Xitron XT560B Digital Milliohmmeter is a dedicated, fully automatic instrument that selects the optimal test current, from 100nA to 100mA DC to accurately measure resistances from 10µΩ to 33MΩ.
The 3465A is a 4.5 digit bench multimeter from Agilent. A multimeter is an instrument used to test and measure alternating current (AC) or direct current (DC) voltage, resistance, and electric current. Multimeters combine voltmeters, ammeters, and ohmmeters. Electricians use multimeters to run diagnostics on batteries, switches, components, power sources, and motors.
