The 4329A is a solid-state insulation resistance meter designed for easy, accurate and direct readings of 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 instantly convertible from ungrounded-to-grounded-sample operation via a simple relocation of the front panel ground strap from “guard” to “+” position.
The 4329A also has a current measurement capability. Minute currents as low as 0.05 pA can rapidly be measured.
Features:
- Wide range: 500 kO to 2 x 1016 O
- Selectable test voltages: 10 V to 1000 V
