W2 kit question for the designer dudes

[NZ0T]

Will the W2 have an accurate calibration procedure that can be performed by a builder with the usual lack of test equipment or will it need to be sen back to Aptos for that like some of the other upscale meter kits?

When will the manual be available to download?

Looks like a really neat device!
