[RE-wrenches] Defective modules

[jay peltz]

Hi Carl,

Here is the link to how Photon measures each module.

http://www.photon.info/photon_lab_modul_ertragsm_en.photon?ActiveID=1289

and

http://www.photon.info/photon_lab_modul_ertragsmAD_en.photon?ActiveID=4382

Can you please tell me how they are doing it wrong, and what the test would look like in doing it right?

Many thanks,

jay
