Default Re: Easy way to measure battery supply current.

"Tricky to measure the "high volume" current with a combined vol/on/off control"

Yes true, but it's a good trick to measure the normal current and to verify the set isn't taking too much, such as for a short battery life fault.
Something I have done in the past is to connect the ammeter to two small squares of kitchen foil, each stuck to opposite sides of a piece of card or thin plastic, a 5 minute make version of the old trick above.
You can slide that in between two of the batteries, which will then obviously connect your meter in. Of course with a PP9 or whatever, you can connect the meter in at the battery clip.
