The HP/Agilent 4329A, is a solid state insulation resistance meter designed for easy, accurate and direct readings of the very high resistance values typically found in synthetic resins, porcelain, insulating oils and similar materials. It is also useful for measurements in electrical components such as capacitors, transformers, switches and cables.

Seven fully regulated DC test voltages (between 10 and 1000 Vdc) are provided as test sources. The 4329A is also instantly convertible from ungrounded to grounded sample operation via a simple relocation on the front panel ground strap from "guard" to "+" position
