Keithley 580 Datasheet
580 Micro-ohmmeter
with Test Leads & Test Lead Pouch
The Model 580 Micro-ohmmeter combines high
accuracy, resolution, and sensitivity with three special capabilities that make micro-ohm measurements easier and more versatile than ever:
1. When measuring contact and connector resistances, it is important not to puncture oxides
and films that may have formed. The Model 580
ensures this dry-circuit condition by clamping
the open-circuit test voltage to 20mV on the
200mΩ, 2Ω, and 20Ω ranges when the 20mV
MAX button is pressed.
2. The Model 580 can test more devices by
enabling both test current polarity and waveform (DC or pulsed) to be selected. When
• 10µΩ sensitivity
• 20mV voltage clamp
• Selectable test current
waveforms
• 3 sets of test leads included
• Optional IEEE-488 interface
• Optional battery

Resistance measurements can be made from 10µΩ to 200kΩ on seven ranges, with 41⁄2-digit resolution
and accuracy to within 0.04% of reading. Ranging can be performed either manually or automatically.
The Model 580 is supplied with three sets of test leads—standard leads, Kelvin probes, and Kelvin clip
leads. For applications requiring portability or line power isolation, an optional battery pack is also available. Digital calibration is possible through front panel controls or over the optional IEEE-488 bus
interface.

using pulsed test current, the Model 580 automatically compensates for thermoelectric EMFs.
Tests on inductive devices are best performed
using DC test current, as this avoids the effects
of time constants on pulsed current resistance
measurements. For temperature-sensitive
components, a single trigger mode of operation
minimizes power delivered to the device.
3. The optional IEEE-488 bus interface permits
operation as a stand-alone unit as well as in a
PC-based system.
