Testing HP 82002A Charger
Hello!

I recently came across several of these chargers. I have no experience with HP calculators or testing electronic devices. I purchased a cheap multimeter and with a little research I believe I tested this charger correctly but I want to double check with the experts here.

A few of the chargers do not give me any readings. However 3 of them all give me the same reading.

I inserted the probe into the + hole and I get a 36 (volt?) reading using the middle hole as a ground. When I test the - hole I get 10. Is this correct? I have a new in the box charger that gives me this same reading as the used one.

I am a reseller and I want to go the extra mile to make sure I have a happy customer.

Thank you all very much. These old calculators are very cool!
