Maximum peak voltage: 5,000V (high-voltage mode for all models) in CS-5000 Series. Maximum peak current: 1,000A (CS-5300 high-current mode). The CS-5000 Series achieves 5,000V of max. peak voltage with the same physical size as the CS-3000 Series. Best suited for the measurement of a power devices that have 3.3kV and 4.5kV withstanding voltage.
