Adwa AD-100 PH meter manual

Does anyone have the manual or directions for this PH meter? My friend gave me this ph meter, and of course lost the directions and of course he never learned how to use the thing... I've tried looking on the net, but no luck as of yet. any ideas on calibrating it or just simply using the thing?

I don't have a manual, sorry. If you can't fine one, we may be able to figure out how to use it anyway.

Anyone have a manual?

Huh. That makes it a little hard without knowing if it is one or two point calibration.

In the absence of having a manual, I'd put it in pH 7 buffer, let it sit one minute, then push calibrate once, then put it in pH 10, and after equilibration, push calibrate again.

If it reads the pH 7and 10 corrctly, you're all set. If it is way off, then maybe it is single point calibration, and just do the first half of the procedure.

It is a two-point meter. Try e-mailing them here for a manual
