DESCRIPTION
The 580 Micro-Ohmmeter combines high accuracy, resolution, and sensitivity with special capabilities for versatile 4-1/2-digit micro-ohm measurements in a wide range of applications. Test voltage can be clamped to 20mV on the 200mohms, 2ohms, and 20ohms ranges to prevent puncturing oxides and films, making the 580 Micro-ohmmeter ideal for dry contact testing. Selectable pulsed or DC drive current and polarity maintains accuracy for measurement of inductive devices and temperature-sensitive resistive components. Seven ranges span 10µohms to 200kohms (manual or autorange), with accuracy to within 0.04% of reading. Settling time is less than one second to within 10 counts on a given range.

Features:

• 10µohms sensitivity facilitates testing of switch contacts, connector pins, and other conductors.
• 20mV voltage clamp assures valid dry contact testing.
• Selectable test current wave forms and polarity assure accurate measurement of temperature sensitive and inductive devices
