Is this ready to use out of the box?

Yes. Read the instructions and immerse it in a glass of water.

how do you calibrate this meter?

I know of no way to calibrate this meter. I tested it on deionized water, tap water, Evian bottled water and sewer water — no difference in readings, I tried testing the water in my toilet bowl by dropping it in and flushing it — also no difference I’m sad to assume.

What is the accuracy of this meter?

The accuracy of this meter is ± 2% F.S. This can be used for testing in the lab.
