Digital Milliohmmeter -
Model 5060-05A

The Digital Milliohmmeter - Model 5060-05A is designed for production resistance testing in an industrial environment. The use of a four-terminal resistance measurement system eliminates the inaccuracies introduced by test lead resistance. When a large number of similar components are to be tested, the front panel thumbwheels permit high and low resistance limits to be set. The limit sensor permits high-speed, automated testing in the milliohm ranges. Indicator lamps illuminate when the resistance of a component is above, below or within test limits. An output relay is triggered to permit the automated rejection of unacceptable components. The Model 5060-05A provides a solid-state chopper stabilized preamplifier to allow full-scale non-destructive resistance testing using only two millivolts of drop across the tested resistance. The combination of this low current operations with the four terminal resistance measuring system permits an accurate resolution of very low resistance's without risk to the test product.
