Description
Overview
The Keithley 580 Micro-ohmmeter is a precision instrument for measuring very low resistance values with exceptional accuracy and sensitivity. It is designed for applications where it is critical not to damage delicate oxide and resistive films on components, particularly in contact and connector resistance testing. The instrument combines high accuracy and resolution with selectable test current waveforms for optimal measurement conditions.
Key Features
- 10μ sensitivity for precise micro-ohm measurements
- 20mV voltage clamp on selected ranges to prevent oxide puncture and ensure dry-circuit conditions
- Selectable test current waveforms: DC and pulsed modes
- Automatic thermoelectric EMF compensation for pulsed current measurements
- Single trigger mode minimizes power delivered to temperature-sensitive components
- Optional IEEE-488 interface for remote control and data collection
- Optional battery operation for field measurements
Applications
- Contact and connector resistance measurements
- Testing of inductive and temperature-sensitive devices
- Quality control and failure analysis in electronics manufacturing
- Laboratory and field calibration work
- Resistance measurements on printed circuit boards and hybrid circuits
