Keysight-Agilent 4329A

The 4329A High Resistance Meter 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 like capacitors, transformers, switches and cables. Seven fully regulated DC test voltages (between 10 and 1000 V) are provided as test sources. Measures 500 kohms to 2x10E+16 ohms.
