(datasheet-js220plus)= # Joulescope JS220+ Datasheet The Joulescopeā„¢ JS220+ is a limited-edition, performance-enhanced version of the Joulescope JS220. The JS220+ achieves ±1 nanoamp accuracy with exceptional temperature stability, all while providing the same best-in-class high-dynamic current range measurement as the standard JS220. The [Joulescope JS220+ User's Guide](../js220plus/index.md) describes the JS220+ improvements, and the [Joulescope JS220 User's Guide](../js220/index.md) describes how to use the instrument. The specification values are also available as [js220plus.yaml](/products/datasheets/js220plus.yaml), which holds the differences from [js220.yaml](/products/datasheets/js220.yaml). ```{include} _js220plus_specifications.md ```
