ION Setup is the recommended software tool (freeware downloadable utility) for updating your meter to this template. Note that these template files are supported by firmware version v400 or higher. For specific instructions on the firmware upgrade process, see the "Upgrading ION Device Firmware" technical note. Be sure to use the correct template for your application. This template release, V4.1.0.0.1, is a follow up to V4.1.0.0.0 which better aligns the template with documented 4-30 features.
