How do you measure quiescent current? (For instance, a Battery connected device)

    Could you provide a circuit? We have a built in circuit plugin tool where you can make a small circuit so that we can see what you're talking about. Where is the battery connected? –  Nov 20 '18 at 00:30

    Roo - Can you be more specific about the problem? For example, is your problem about *physically* making the connection in series with the power source / battery? Or is it a *measurement* problem, and your existing equipment can't measure those low currents? Or something else? – SamGibson Nov 20 '18 at 00:32

You measure it like you would active current use. Nothing changes. Quiescent current is the amount of current a circuit, that is doing nothing, takes. You would connect it to a ammeter just the same. For very low quiescent currents, you may need a more precise or quality meter. Some devices or circuits have IQs in the micro and nano amp ranges, which a cheaper meter would not be good enough to register properly.
