Eleaf LCD Tank o Meter

[paulrm]

I have received an Eleaf tank o meter from edampf-shop, who I'd thoroughly recommend, this being my first such meter I'm not sure how they are usually configured, however, to my surprise, and delight, this one measures voltage, ohms and wattage under load which will save me messing about with my multi meter; is this a normal configuration? Of course the on site description does explain all this but why on earth would I read a description,  , it 11.95 euros and I also purchased an eleaf Lemo atomiser with which I am also delighted and spread the postage.
