Hi,

I just got my USB meter delivered any tried it out immediately on different devices. Voltage gets measured just fine however the current counter (and consequently power and capacity counters) remains zero. While the devices actually are being charged I guess there actually is current flowing.
I already tried zero calibrating the device to no visible change.

Any advice on how to proceed on this? TIA!

Problem solved: Obviously voltage measurement works with input from both directions while current measurement only works if the male USB connector is connected to the power source.
In my test setup using a given cabling I had used an adaptor that would connect the power source to the female USB connector of the multimeter and the device to charge to the male USB connector. Voltage applied and the devices did charge.
My second test setup had things reversed and suddenly the current and consequently power and capacity were measured. Problem solved.

Perhaps it would be an idea to mark input and output directions in the manual.
