The Keithley Model 580 is a 4 1/2-digit resolution autoranging micro-ohmmeter with a ±20,000 count LCD. This unit is designed for low resistance measurement requirements from 10µOhm to 200kOhm. The model 580 has an analog output/IEEE-488 interface option, Model 5802.

SKU: KEI580 Category: Tag: Brand:


Low Resistance Measurement – Seven resistance ranges from 200mOhm to 200kOhm with 10µOhm resolution on the lowest range.

Relative (REL) function – Allows measurements to be made as compared to a previously measured resistance.

Digital Calibration – Performed from the front panel or over IEEE-488 bus. Non-volatile RAM retains calibration constants.

Trigger (TRIG) – Allows operator to make single resistance measurements at desired intervals.

Dry Circuit Test – Limits test voltages to 200mV to protect sensitive contact junctions.

Drive – Select pulsed or DC Source current.

Polarity – Selcts positive or negative SOURCE current.
