The resistance of my Belkin anti-static wrist strap shows 0.983, but how do I know that I am grounded by attaching it to computer power supply alone? See the picture below.
How do I know if that resistance is absorbed by the grounded contact? Must I touch a metal plate below the strap with one lead and power supply with another lead?
UPDATE: I wanted to know if there is a contact between wrist strap and power cable's grounded contact through power supply. Since wrist strap works, i wanted also to know that grounding it to power supply and then connecting to power outlet will work as well so i touched wrist strap's metal plate with one lead and grounding contact of power cable with another lead and saw same resistance as mentioned above. This means that everything works.
